Chickens Laying Soft Eggs? 6 Reasons Why (And What To Do)

If you have chickens laying soft eggs and aren’t sure what to do about it, you’re in luck because I have plenty of answers.

 

Soft eggs, also called shell less eggs, soft shell eggs, partially shelled eggs, or rubber eggs, can be a sign of a few different factors, such as illness, age, and diet.

 

Some of these factors are out of your control (like age), some aren’t (like diet), and some factors are a bigger cause for concern than others (like illness and stress).

 

We occasionally get chickens laying soft eggs on our farm, and they’re simultaneously cool and disturbing.

Back many years ago, the first time we saw a soft egg, we didn’t know what to make of it.

 

Our latest batch of chickens were young pullets that just started laying.

 

One of the first eggs we got from these layers didn’t have a shell – just the thin membrane, albumen, and yolk. And it had gotten squished and spread everywhere.

 

We were so disappointed – we were looking forward to gathering eggs for the first time!

 

But the hen’s subsequent eggs were healthy and normal. Whew!

 

So, chickens laying soft shell eggs can happen for a variety of reasons, which we’ll talk about below.

 

What age is your hen?

 

One of the first things you should look at if you have chickens laying soft shell eggs is the age of your flock.

 

When pullets first start laying, they’re more likely to lay soft shell, eggs missing their shell, or thin shelled eggs than older laying hens.

 

This can be for a couple reasons: your chickens don’t yet have enough calcium in their diet or their bodies are getting used to laying, and haven’t quite caught up yet.

 

If you’ve been feeding your older pullets a grower ration, and they lay a soft egg, then switch them to a layer ration. The grower feeds don’t have as much calcium as a layer feed, so your chickens might not have enough calcium in their diet to support building an egg shell.

 

Simply switching to a layer feed or offering her a calcium supplement will likely solve the problem, and your chickens will probably start laying normal healthy eggs.

 

If your chickens already have enough calcium in their diet (if you offer them a supplement already, for example), then it’s possible her body is just getting used to the rigors of laying and didn’t properly apply the calcium to totally encase her egg.

 

As long as she seems healthy and starts laying normal eggs, it’s probably nothing to worry about.

 

Calcium deficiency

 

We’ve touched on calcium deficiency already, but if your chickens are older and laying regularly but suddenly give you soft eggs, then it’s time to look at their calcium intake.

 

One of the most frequent causes of laying thin shell or soft eggs is a diet low in calcium. While most quality layer feeds have extra calcium in them, you should still offer a supplement just to make sure your hens get enough.

 

If your laying chickens aren’t eating enough calcium, soft eggs aren’t your only concern. In order to produce eggs, hens must draw calcium from somewhere.

 

If they can’t get it from their diet, your chickens will start pulling it from their bones, which can lead to another set of health problems.

 

Oyster shells or toasted egg shells are two supplements that can help provide enough calcium for your flock.

 

Can be a sign of stress

 

Stress can also lead to soft eggs or thin egg shells. Stress can include:

 

  • Environmental stress
  • Heat stress
  • Predator stress

 

Environmental stress

Environmental stress can be anything from a coop or run that’s too small and packed with too many chickens to stress from roosters mating too frequently.

 

If your flock’s diet is calcium-rich, then examine their living situation. Are your chickens cooped in a small area all day? Do they have 10 square feet of space? Are roosters picking on her?

 

It’s possible her environment is causing her stress, and the calcium is being diverted from creating egg shells to supporting your hen’s bodily health.

 

In one memorable experience on our farm, one of our chickens watched a dog kill her flock mate. The surviving hen never laid well after, and laid a couple rubber eggs. Since her diet was good and she was healthy, environmental stress seemed to be the cause.

 

Heat stress

If you’ve ever wondered “Why did my chicken lay a soft egg” when it’s warm out, then heat stress might be the culprit.

 

I’ve learned that hot weather can be a big factor in thin shelled eggs or shell less eggs. Heat is hard on chickens, much more so than cold weather.

 

Chickens have a natural body temperature at around 106 degrees, and don’t have the same effective cooling mechanisms that humans have. So, they feel the heat a lot more than we do, and that can temporarily effect their laying ability.

 

There’s not much you can do to control the weather, but you can offer your hens some relief from the heat. Make sure they have enough water, and a cool area to rest in.

 

If you think heat stress can be effecting your flock’s egg production, then start offering nutritious treats like frozen fruit, mealworms, etc to keep their diet up to snuff.

 

It’s also a good time to offer a free-choice calcium supplement to ensure they’re getting enough calcium. Hot weather can lead to dietary deficiencies because chickens start using nutrients to battle stress and less for laying healthy eggs.

Sign of Illness

Soft eggs can also be a sick chicken symptom. If your hen’s body isn’t feeling healthy, she will use dietary nutrients to fight off the illness – and not on creating an egg shell.

 

A soft egg can indicate any sort of illness, from a bacterial infection to a virus to trauma, and more. If you think your hen is sick, then only a vet can diagnose her exact illness and recommend a treatment.

 

In my experience, once the illness is resolved, the hen starts laying healthy shelled eggs again.

 

Sometimes soft shell eggs just happen

 

Let’s say your flock’s diet is calcium-rich, you don’t see any environmental factors, heat stress, or signs of illness, but your chickens lay a single soft egg. It’s possible the rubber egg is just one of those things that happen.

 

Chickens are living organisms. Like people, sometimes things just go awry, and there’s no logical explanation.

 

Perhaps her body just sent the egg through the oviduct faster than normal…as long as the hen seems healthy and it’s only one chicken egg without a shell, I usually don’t worry too much about it. Things happen!

 

Can you eat a soft shell egg?

 

A question I’m frequently asked is whether soft eggs can be eaten. Honestly, usually when I come across a egg with just the membrane, if it’s intact, I give it to my pigs.

 

One of the purposes of the shell is to keep bacteria and other pathogens out of the egg. Without it, there’s a chance it’s been invaded by germs I don’t want to eat.

 

So personally, I don’t eat them.

 

Soft eggs can be disturbing. But there’s a lot of ways to fix the problem, and it’s not necessarily a sign your flock is unhealthy.

  • Got a soft-shell duck egg this morning (Oct 3 2016), put it in the incubator. Will keep you posted!

    • We are first timers and enjoy our girls. We have had 2 soft shells and a very tiny soft she’ll.
      Having read your page we can now look at what we are doing.
      Thanks

  • I’ve gotten at least 20 soft shelled eggs in all my time raising chickens.

  • I had my daughter looking after our 2 chickens they have only started to lay the last couple of weeks for a couple of days she had one soft shell and I have found one soft shell egg today when I came home
