A very common question I get is whether a chick is a rooster or a hen and how to sex baby chickenss. In this article, I’ll show you some ways you can tell when it comes to sexing chicks!

When it comes to getting chicks, one of the most exciting parts is waiting until your pullets grow up to be layers.
Buuutttt….it’s pretty much a given that at some point in your chicken keeping career, you’re going to wonder about the chicken sex: whether the chicks you picked up at the local farm store are REALLY pullets (which will grow up into hens), OR little roosters in disguise.
We’ve all been there – thinking our chicks will be great layers, only to find out 7 months later, it would take an act of God for them to lay eggs.
There ARE some ways you can tell if your chick is a rooster or hen and how to sex baby chickenss – they’re not 100% accurate but they’ll help you take a good guess.
Chicken sex: How do I tell whether my chick is a rooster or a hen? There’s a few ways:
- Check the vent
- Look at combs & wattles
- Watch feather growth
- Look at down color
- Examine behavior
- Listen for crowing
We’ll cover all of these in this article!
Check The Vent
Now, before I explain this one, let me state for the record that unless you’ve gone through extensive training to vent sex chickens to tell if your chick is a rooster or a hen, I suggest skipping this step.
Vent sexing involves squeezing out manure (if needed) then checking the vent for male or female “parts,” and it’s the only 100% surefire way to tell if your chick is a rooster or a hen.
However, as you can imagine, this is fairly invasive, and you could possibly permanently harm or kill your chick – so I would leave this method to the experts.
Professionals who sex chicks for a living go to school for years to learn how to do it properly.
Look at Combs & Wattles
While this is definitely not a 100% surefire way for how to tell a rooster from a hen (some roosters are pretty androgynous and some hens like to crow), I’ve found it to be pretty accurate.
The photos below are of 2 chicks from the same hatch – both California Whites, same age, purchased at the same time.
At the time of these photos, these two chicks were about 2 weeks old.
The comb of one chick is more pronounced than the other chick. This is a fairly accurate indicator that the chick with the more pronounced comb is likely a rooster.
Another indicator is the wattles. In young roosters, the wattles grow longer faster, and are redder than pullets. So, if you start to notice your chicken’s wattles when they’re fairly young, it’s possible you got a rooster in your hatch!
Note this only works with breeds that grow regular combs – so pea comb breeds might not exhibit these characteristics at a young age.
Watch Feather Growth
Feather growth is another way you can try for how to sex baby chickens. Female chicks – aka pullets – grow feathers faster than males. Learn more about chicken feathers here.
This only works for about the first 3 days of life – after that, the feather growth on each chick will be about the same.
Pullets in some breeds grow their primary feathers faster, so their secondary feathers will be shorter. Young roosters will have feathers about all the same length.

Feather sexing is also sometimes breed specific, so if you don’t notice that some chicks grow feathers faster than others, don’t worry, you still might have pullets!
Once the chicks are older – about 12 – 16 weeks, you’ll also start noticing young roosters develop saddle feathers – which hens won’t have. Here are more tips on caring for chicks from 7-16 weeks old.
Some breeds will produce chicks with different color down or different markings based on their sex.
For example, Black Sex Link and Red Sex Link pullets will have different markings than roosters of the same breed. This is a characteristic selected for by breeders so they can tell the sex of the chicken right after it hatches.
One such match that will produce sex link chicks is crossing a Rhode Island Red rooster with a Barred Rock hen.
In this cross, male chicks will have a white dot on their head while female chicks will be solid black.
Sex link chickens don’t necessarily breed true – so if you cross a black sex link rooster with a black sex link hen, there’s no guarantee the resulting chicks will also be sex linked.
This is, again, breed specific – so it will only work with chicks of certain crosses.
Now, this is just drawn from my own personal experience, but I believe you can also start to tell the sex of baby chicks based on behavior.
Naturally, this isn’t universal, and pullets might exhibit some of the behaviors we’ll discuss, but I’ve noticed over the years that roosters will do somethings that pullets naturally won’t.
- The stink eye
Now let me explain. The stink eye is when you look at a chick, and they look up at you, cock their head to one side, and stare you straight in the eye.
I’ve noticed that it’s typically roosters that are this bold. Pullet chicks tend to not be so aware of their surroundings, or look to other chicks for behavioral guidance and security.
I’ve noticed this in many different hatches over many different years, and it’s a clue I rely on to determine the sex of baby chicks.
You might also notice some chicks fighting earlier in their lives than others. For example, you might notice them flying up at each other, bumping chests like football players, then going back to their corners.
In my experience, these are young roosters testing their strength against other roosters.
Listen For Crowing
Something else you might notice is young chicks testing out their lungs. Young roosters will sometimes crow very early in life – as early as 4 weeks in some cases.
While there ARE hens that’ll crow, it’s not usual, so if you notice your chick trying to make a little baby crow (maybe succeeding, maybe not!), you might just have a young rooster on your hands.
While nothing will ever be 100% certain except vent sexing, hopefully now you no longer wonder how to sex baby chicks!
