How do chickens differentiate between roosters and hens (detailed introduction)

There are several ways you can usually tell a rooster from a hen during the early stages of a chick's life, although these methods are not entirely accurate as there may be some exceptions for different breeds of chicks. Here are some common identification methods:

Feather Color: In some breeds, there may be slight differences in feather color between roosters and hens. For example, some breeds of roosters may have brighter feathers, while hens may have duller feathers.

Tail Shape: In some breeds, roosters and hens may have different tail shapes. A rooster's tail is usually longer and upright, while a hen's tail may be shorter and slightly raised.

Crown feather development: Some breeds of roosters and hens may have differences in the development of the crest feathers on their heads. The comb feathers of a rooster are usually more developed and full than those of a hen, which may be smaller.

Leg and paw shape: Roosters and hens can also have different leg and paw shapes. Roosters usually have thicker legs and larger and stronger claws, while hens have thinner legs and smaller claws.

It is important to note that these characteristics may not be obvious in the early stages of chicks, so it may be necessary to wait until they are older to more accurately distinguish roosters from hens. In addition, there may be some exceptions and individual differences among different breeds of chicks, so the most reliable and sure way is to wait for them to grow up and show the sexual characteristics of adult chickens, such as color, feathers and behavior.
