How To Tell If Eggs Are Good (5 Best Ways)

How To Tell If Eggs Are Good (5 Best Ways)

Wondering how to tell if eggs are good? We’ve all been there. 


You open the refrigerator, excited to cook a delicious omelet or a healthy scramble. You open the egg carton, only to notice that the expiration date stamped on the cardboard has long since passed.


What’s an egg-lover to do? Don’t rush to toss the carton in the trash.


A stinking, rotten smell of sulfur is a telltale sign that your eggs are no longer edible, but it’s not the only technique that you can follow. Expiration dates are good estimations of how long you can let eggs sit in your refrigerator – but as mere approximations, they aren’t always reliable on their own.


Here are some of the best methods of how to tell if eggs are good – with or without an expiration date.

When Do Eggs Usually Go Bad?

Believe it or not, not all eggs go bad at exactly the same time – and you can’t always trust the posted dates. 


Remember that the estimated freshness and longevity of eggs is determined by the American Egg Board, an association whose job it is to increase national demand for products on behalf of U.S. egg producers – it wants you to buy more eggs, so the dates are going to be more conservative. 


Nevertheless, these dates are good first lines of defense against food borne illness. Eggs can usually last in the refrigerator for about 30 days after packing. When you look at your egg carton, you may see a variety of dates, including a sell-by, expiration, or pack-by date. Usually, you’re safe to eat eggs within 21-30 days of any of these dates. 


The quality of the egg will usually start to decline after a certain date, but will still usually be safe to eat. Unfortunately, if you are eating your own farm-fresh eggs, determining freshness and safety without an expiration date can be a bit more tricky. 


Usually, raw whole eggs are safe to eat for about four or five weeks, while raw eggs that have been processed in any way (for example, separated egg whites and yolks or hard-boiled eggs) are only safe for about two to seven days. Once heat has been applied or the eggshell has been removed, there is a greater likelihood that bacteria is going to interfere with the freshness of the egg.


How To Tell if Eggs are Good Past the Expiration Date

Unless you’ve cooked the eggs or altered them in some way, don’t toss them just because the expiration date has passed. As with meat and produce, it’s pretty easy to tell whether your eggs have gone bad without needing to look at the expiration date. 


Remember, refrigeration preserves the quality of the egg quite dramatically, so as long as your eggs have been stored properly, you have a bit of extra insurance.


Here are some easy methods of how to tell if your eggs are good.

How to Tell How Old Your Eggs Really Are

This is GENIUS! Chicken eggs only stay good for so long….

Posted by I Love Backyard Chickens on Sunday, September 24, 2017

Step One: The Visual Inspection

If you’ve already sniffed your eggs and can’t tell whether they’ve gone bad or not, using your eyes is another great way to tell whether your eggs are safe to eat. 


Before cracking your egg, make sure the shell is not cracked. A crack can not only indicate the presence of bacteria, but a crack can cause an egg to spoil more quickly than it would if it were contained in an unbroken shell.


You should also look out for a slimy or powdery appearance on the egg. A powdery appearance can indicate mold, while sliminess can be a sign of bacterial growth. 


Step Two: Eggs in the Bowl 

It sounds like the name of a fun Easter scavenger hunt, but this method simply refers to the act of placing your egg in a bowl of water to determine whether it is still fresh or not. This is also called “the egg float test.”



Eggs are porous, and the liquid that is contained inside the egg evaporates over time, replacing the liquid with additional outside air. When the egg fills with air, it will float. Therefore, by placing an egg in a bowl filled with cold water, you can determine whether it is safe to eat. An egg that sinks to the bottom and lays flat on its side is still fresh, while on that floats to the surface is no longer fresh.


What if your egg stands on one end at the bottom of the bowl? It’s still probably safe to eat, but it won’t be as fresh. 


Step Three: Audio Test

The audio test of determining egg freshness works according to the same science as the one above – older eggs begin to fill with air. 


To conduct the audio test, simply hold an egg to your ear and shake it. You’ll need to have good hearing, but if you can hear a sloshing sound inside the egg, you need to toss it – it’s not safe to eat.

Step Four: Crack ‘n Sniff

Here’s where we get more advanced. Perhaps you’ve tried the steps above and aren’t convinced that your egg is fresh – but you also don’t know for sure that it’s spoiled. Here’s what you need to do.


Crack the egg into a pan. Before you continue cooking, it’s important to make sure the egg isn’t loaded with nasty egg-borne bacteria. 


Take a close look at the egg. If it’s fresh, the yolk will be a bright yellow or orange and the whites should stay right in place. They may spread out a little bit, but they won’t be overly runny. Similarly, the yolks of older eggs may appear flattened or discolored. In particular, keep an eye out for any black, blue, pink, or green shades in the whites and yolk – this can be a sign of bacterial growth.


If either of these criteria is evident when you crack your eggs, discard them. If you still aren’t convinced, give the questionable egg in the pan a sniff. If it doesn’t have a smell, it’s probably safe to eat, but you might want to hard boil the rest of the eggs as they’ll taste fresher this way.


Step Five: Flashlight Test

If you have ever hatched your own baby chicks at home, you might already be familiar with the flashlight test, also known as “candling” an egg. You can easily use the candling or flashlight method as a way to tell if eggs are good in the kitchen, too. 


To do this, venture into a dark room with a flashlight. Any small flashlight or reading light will do. Place the flashlight so that the light is shining up into the large end of the egg. Tilt the egg and move it quickly from left to right. 


This will allow the contents of the egg to be illuminated. Look closely at what’s inside. You should be able to see the air cells in the egg. The fresher an egg is, the thinner and smaller the air pockets will be. 


How to Keep Eggs Fresher – For Longer

Do you feel as though your eggs begin to spoil as soon as you get them home from the grocery store? If so, you could be making a simple mistake in storing them. Although some refrigerators are equipped with egg compartments in the door, this is actually not the best place to store them – they will experience too many temperature fluctuations here. 


Instead, store your eggs in the main part of the refrigerator, where it’s colder and the temperature is more stable. If you are eating eggs from your own chickens, avoid washing them until you’re ready to use them. 


The outer layer of the egg contains bloom, a covering that helps prevent the buildup of bacteria and also works to preserve freshness. And don’t worry if you see a blood spot in the yolk. It’s perfectly safe to eat and is simply a sign of a fertilized egg.


You can also freeze your eggs if you have more than you know you will use in a given time frame. Frozen eggs will cook up just like fresh eggs, but the freezing process will help to keep your eggs fresher for longer. 


Why It’s Important to Know How to Tell if Eggs Are Good

You may eat eggs every day, or they may be an occasional treat in your household.


Whatever the case may be, it’s important for you to know how to tell if eggs are good or not. Not only can these strategies prevent you from unnecessarily throwing away safe, delicious eggs, but they can also help keep you safe from food borne illnesses.


Food borne diseases that are caused by bacteria, such as Salmonella, often produce eggs that look, smell, and appear completely normal. Therefore, it’s not only important to conduct these other tests but to make sure you completely and fully cook your egg to a safe temperature before you go ahead and eat it. 


And remember, even if you can’t eat your eggs because they’re past their prime, there are plenty of ways to avoid wasting them. Use the eggshells in your garden as a fertilizer or pest repellent, and in the meantime, maybe whip up some cereal for breakfast instead.


Genius After School Activities For Kids

Genius After School Activities For Kids

I know all moms dread hearing the phrase “Mom I’m bored” and honestly I’ve heard that phrase way too many times.

Back to school is great for me because I get 8 precious hours all to myself again! But once the kiddos get home, they want a snack, and then comes the dreaded “I’m bored mom.”

So I’ve come up with some activities that not only entertain my kids, but also keep them active (and away from video games!)

I’ve also noticed that kids tend to focus a lot better on their homework if they do a fun activity before starting into the huge pile of homework that they get everyday.

After a long day at school I think they need something fun (and active) to do before having to start into all their homework. (Am I the only who thinks that kids get way too much homework nowadays? They have so much homework, it’s crazy!)

One thing I also love about some of these activities is that they’re also educational! Many of them are science experiments and so your kids get to learn something new while also having some fun!

So here’s my list of my favorite after school activities for kids that will keep them entertained for hours!

Egg Float Test

So of course as a chicken mama this had to be the first activity on my list. The egg float test is a useful test for telling if your eggs are fresh.

You can watch the video below to learn how to do this experiment. Basically, if you place an egg in a glass of water and if it sinks to the bottom it’s fresh and if it doesn’t it’s an old egg!

While this test is great for figuring out if your eggs are still fresh, it can also be fun for kids to experiment. You can explain why the fresh eggs sink and why the old eggs don’t sink (if you don’t know why I have an entire article here all about the egg float test)

You can mix this experiment up by adding salt to one of the glasses. Add about 8-10 tablespoons of salt to a glass of water and stir until the salt dissolves. Once the salt has dissolved you can place an egg in the salt water and one egg in a glass of normal water.

The salt water egg will float to the top while the other egg will sink to the bottom! Fun right? It’s a fast and easy experiment for your kids.

Dissolving Egg Shells In Vinegar

This is another super easy activity that’s fun and educational for your kids. If you place raw eggs in white vinegar for 24-48 hours the shell dissolves leaving the membrane of your egg intact.

All you need to do is place several raw eggs in a container and cover them completely with white vinegar.

Put them in the fridge for 24 hours and then dump out the old vinegar and fill the container with fresh white vinegar.

Let the eggs sit in the refrigerator for another 24 hours and then the egg shells will be dissolved!

What’s left is the membrane of the egg enclosing the yolk. Your kids will love the “squishy” egg that results! It’s also fun because these “naked eggs” bounce! Don’t drop them too far or you’ll be dealing with a mess. And be careful with these eggs…the membrane isn’t super strong so they’re pretty easy to break…and they’ll make a HUGE mess if they do.

What’s great about this activity is that you can teach your kids about the “anatomy” of eggs. With the shell dissolved it’s easy to show your kids the membrane and the inside sections of your eggs.

You can learn more about what’s inside your eggs here and then teach your kids all about it with this fun experiment!

The Egg Drop

Ok this is the last egg themed activity, I promise! This activity is a classic…I’m pretty sure I did this one multiple times throughout my elementary school years. It’s probably best for older kids, maybe 8-9 years old and up.

The basic concept of this activity is to create a protective box for a raw egg that will protect it from breaking after a big fall.

It requires your kids to think creatively. They have to come up with a way to protect their egg from breaking.

Just provide them with some different materials that they can use to try and protect their egg. Anything will work: cardboard boxes, Styrofoam, packing peanuts, felt, wrapping paper, duct tape…your kids can use a variety of materials to protect their egg from the drop.

After your kids have created their own personal protection for their egg, then you have to test it out. I did this as a kid and we totally dropped our eggs off of the roof of our two story elementary school…and it was awesome. But you could just drop the eggs from anywhere (make sure it’s somewhere safe! and easy to clean!)

After you finish see what worked best in protecting the eggs from breaking. And then your kids can try again!

Solar Oven

This is a fun activity for your kids to learn more about heat from the sun and learn how to make their own solar oven! All you need is some tinfoil, plastic wrap, black paper, an old pizza box, and some newspaper!

You use the pizza box to create a small oven for your food! It’s pretty simple to make and your kids will think it’s awesome that they can cook food using the sun!

You can follow these step-by-step instructions on how to build a solar oven

After your oven is built you can start cooking food! Don’t cook anything that’s raw…there’s no guarantee that it will get completely done! I recommend that you choose a food item like nachos, or s’mores. Your kids will love the yummy snack, and they’ll be thrilled that they got to cook using the sun!

Rainbow Soap Foam

I love this activity! Soap foam is not only fun, but it’s a great sensory activity for kids.

One thing that’s really important to me is to incorporate sensory activities for my kids into their daily schedule. That’s why I love this rainbow soap foam and these outdoor decorations that double as sensory activities.

This foam is quick and easy to make and your kids will love being able to play in it. I recommend that you do this activity outside because it will get messy, but personally I think the fun is worth the mess:)

Obstacle Course

I loved obstacle courses as a kid. I would set up elaborate courses with my siblings and we had so much fun! Obstacles courses are great for your kids because they’re fun and active! A fun indoor obstacle course is to create a maze with streamers through a hallway (see picture below!) Your kids will feel like they’re a spy trying to sneak through lasers and you’ll get a good laugh out of watching them try to get through!

Galaxy Jar

Um yes. This is awesome! I love these DIY galaxy jars! They’re fun to make and your kids will LOVE them!

Here’s the tutorial here: DIY Galaxy Jar Tutorial

Farm Themed Activities

Who doesn’t love farm activities? Check out this post here for a list of fun farm activities you can do with your kids. Making butter, old fashioned games etc. your kids will love these fun activities!

Ice Cream in a Bag

I’ve shared this recipe before, but I’ll share it again because I love it! You can make your own homemade ice cream using Ziploc bags!

This ice cream is SOOO fun to make and it is super simple too! You mix the ingredients together and then toss a bag around for 20 minutes. It’s great for a game of hot potato or catch and your kids will love getting to throw around the bag!

Here’s the recipe:


1 heaping T of instant pudding (in the flavor of your choice)

1 t vanilla

1/4 c of sugar

3/4 c. cream

1 cup milk

2 c rock salt

4 cups ice


You’ll need 2 qt sized Ziploc bags, 2 gallon sized Ziploc bags, duct tape, newspaper, and some plastic grocery bags.

In one of your qt sized Ziploc bags mix together pudding mix, vanilla, and sugar. You can choose the pudding mix of your choice! You can even experiment and mix flavors together. If you’re doing two different flavors just do a 1 ½ teaspoons of each flavor.

Close the bag (make sure it is closed tight!) and squish the ingredients together.

Next add cream and milk into the same ziploc bag and then squish all of the ingredients together again.

Place bag your qt sized bag into another qt sized bag (the extra bags are to stop the ingredients for leaking all over. If your kids are rough with this kind of stuff, add extra bags and newspaper for more protection)

Place bags inside of a gallon sized Ziploc bag. Place 2 cups of rock salt and 4 cups of ice in the gallon sized bag, spread equally on either side of your qt sized bags.

Place this bag into another gallon sized bag and begin to wrap with newspaper. I wrap it with at least 5 layers of newspaper and then tape it all together with duct tape. Then I wrap a couple grocery bags around the outside for extra protection and tape them down with duct tape.

Then comes the fun part! Toss the bag for about 15-20 minutes. Then your ice cream will be ready! If you unwrap it and it isn’t quite done, just wrap it up again and keep tossing it!

Before I open the last bag that has the ice cream in it, I recommend that you wash off the bag with cold water. This gets off any of the rocks salt that might have been on the bag and prevents you from having salty ice cream!

This makes a super fun and easy activity for your kids that they will absolutely love!

Well I hope you like some of these activity ideas for you kids! Which one was your favorite? What activities did you do as a kid that you loved? I’d love to hear about it in the comments below!

Do Eggs Go Bad? How Long Do Eggs Last? Here’s What You Need To Know!

Do Eggs Go Bad? How Long Do Eggs Last? Here’s What You Need To Know!

We all know fresh eggs are best, but what about whether they spoil? Do eggs go bad? Can eggs go bad?? How long do eggs last??

 Yes, eggs can go bad, but do you know WHEN do eggs go bad or how long do eggs last? In this article, I answer all these questions.

We’ve made the mistake every so often of forgetting that we left eggs on the counter, or one of the kids hid an egg in an undisclosed location. We’ve always found them eventually – and it’s not been a pleasant find.

When eggs rot, not only do they stink – they turn black and gooey. It’s really an experience you’re better off not having.

In this article, I’m going to show you how you can keep your eggs as fresh as possible, how you can tell if eggs are bad, and answer the age-old question “how long do fresh eggs last?”

Do Eggs Go Bad? Here's What You Need To Know!

Why Do Eggs Go Bad?

Eggs go bad even when they’re refrigerated – they definitely have an expiration date. It’s not usually the date printed on the carton (if you happen to have bought eggs at the store – if you did, consider getting chickens).

How long do eggs last? It can take quite a bit longer for eggs to go bad, but they will, beyond a shadow of a doubt, spoil. When eggs are laid, they’re covered with something called “the bloom,” a cuticle or natural covering that keeps bacteria out of the egg, keeping it fresher for longer.

It’s an evolutionary advantage that helped chickens reproduce successfully – and egg that can easily be contaminated won’t hatch or will hatch weak and sickly chicks.

Store-bought eggs (at least in the US) have had the bloom removed – so if you’re wondering “how long do eggs last?” not only do eggs go bad, store bought eggs will rot faster, even when refrigerated. This is because they’re more susceptible to bacteria entering through the shell and contaminating the albumen (egg whites) and the yolk. Not a good thing!

Farm fresh eggs – that haven’t had the bloom removed – will still spoil, but at a slower rate.

Do Eggs Go Bad? Here's What You Need To Know!

How Do Eggs Go Bad?

As the bacteria enters the egg, it will reproduce and grow, feeding on the nutrients – particularly if you’ve left the eggs on your shelf and not in the refrigerator.Eventually, so much bacteria gets into the egg that the insides turn black – and very stinky. Learn more about the insides of a chicken egg.

If you wonder “how can you tell if eggs are bad,” there’s a few different ways. Does it pass the smell test (in other words, does it stink)? If you smell anything – just toss it. Fresh, healthy eggs don’t smell at all.

Another option is the Egg Float test – you can learn how to that in this video:

How Long Do Eggs Last Unrefrigerated?

You might be wondering how long you can leave eggs out before they become rotten. There’s a few different answers to this questions. Fresh eggs with the bloom on can last quite a while – 2 to 3 weeks. However, they WON’T be fresh or as healthy for you..

You’ll notice the air sac at the “fat” end of the egg is larger. You’ll also notice, when you crack them, that the yolk might be runny (this is because the membrane holding the yolk together weakens over time) and the albumen (egg whites) are clear – all signs that your egg is no longer fresh nor as nutritious.

So how long do refrigerated eggs last? According to the United States Food Safety and Inspection Service, part of the USDA, which has also answered the question “do eggs go bad?,” refrigerated eggs can still be refrigerated 4-5 weeks after their expiration date – so for fresh but refrigerated days, they can last up to 2 months inside the refrigerator.

If you want to preserve fresh eggs for long term storage, here’s an article that shows you how.

How long are eggs good for: Conclusion

So, if you’ve been wondering “do eggs go bad?” or “how long do eggs last?” you can feel quite sure that as long as you leave the bloom on and keep them in a cool area, they’ll last quite a while.

Egg Float Test: Is That “Fresh” Egg is Good Or Bad?

Egg Float Test: Is That “Fresh” Egg is Good Or Bad?

Not sure if that “fresh” egg is good or bad? Try the egg float test!


Why do you need to know about the egg float test? Chickens are masters at hiding their eggs if they want.


Every so often, I come across a nest of “fresh” eggs on the homestead – and I have no idea how long they’ve been there, and if they’re good or bad.


Chickens like to hide their eggs in dark, tight places.




It’s an evolutionary thing – eggs that are hidden are less likely to be snagged by a predator.


At the same time, if a chicken wants to hatch eggs, which requires sitting for long periods of time, a dark place is best – she’s more likely to be left alone.


But let’s say you come across a nest, and aren’t sure how old the eggs are, and whether you should just toss them.


Want to know how to tell if eggs are good? That’s where the egg float test comes in!


If you’ve never tried the egg float test, it’s a great and visually easy way to tell if eggs are fresh.


Also, if you have store-bought eggs in your fridge that are expired, it’s worth trying the egg float test to determine if they’re okay to use.


Try the egg float test to see if your eggs are good or bad. Come across a nest of eggs and don't know if they're good or bad? Test them! From FrugalChicken


So, how do you perform the egg float test?


The egg float test is easy.


First, grab a cup of cool (not ice cold and definitely not hot) water.


If you want to try the egg float test using a mason jar, make it easy on yourself, and use a wide-mouthed jar so you can get the egg out easier.


A cup of water works well, too.


To complete the egg float test, just gently insert your egg into the water.


According to the egg float test, if your eggs rise to the top of the water, they’re too old to use.


But if they sink, they’re fresh and still good to eat.
Of course with anything there’s a catch.


What does the egg float test mean if your egg sort of floats, but sort of sinks?


If your egg suspends on one end, it’s technically still okay to eat, but you need to use it soon. 


Personally, I usually toss these eggs to my pigs, since there’s typically fresher eggs available.


I know the pigs appreciate them.


And remember…


Once you’ve put the egg in water, you’ve stripped off the bloom, which means air can get into the egg quicker. (Learn more about cleaning eggs here).


So, if the eggs sink, you’ll probably want to use them sooner rather than later. (Learn more about how long eggs stay fresh).


So, what’s the science behind the egg float test?


Good question.


Egg shells, as you might know, are porous, meaning they let air into them. (Learn more about the anatomy of an egg here).




The fresher an egg is, the less air it has inside of it, so it sinks.


Old eggs, however, have more air in them because oxygen has had time to permeate the shell. So, they float.


Because of all this, the egg float test is considered an accurate way to test your whether those eggs you found are okay to eat, or if you should just toss them.


Other “Freshness” Tests: How to Tell if Eggs are Good


There are a couple other ways besides the egg float test to tell if the eggs you found are fresh.


One option is to candle the eggs, just as you would if you were to hatch them.


In this test, you’re looking to see how intact the yolk is (the more intact the more likely it’s fresh).


And, similar to the egg float test, you’re looking to see how much air is inside the egg (the more air space, the older the egg is).


Another test is to hold the egg up to your ear.
If you hear a lot of movement, the egg is said to be old, but if you don’t hear anything, then the egg is fresh.


Personally, I prefer the egg float test, and I have more experience with it.


Now that you’ve determined your eggs are fresh using the egg float test, how about some egg recipes to help you use them up?
