How to Determine the Gender of Baby Chicks


Welcoming baby chicks into your flock is an exciting and rewarding experience for any poultry enthusiast. However, one of the most common questions that arise during this period is, “How can I tell if a baby chick is a rooster or a hen?” How to determine the gender of baby chicks, or sexing baby chicks, can be a challenging task, but with some knowledge and keen observation, you can confidently identify the gender of your adorable new additions. In this article, we’ll provide you with practical tips and tricks to determine whether your baby chick is a rooster or a hen.

  1. Observe Feather Development:

One of the primary indicators of a chick’s gender is its feather development. Around 2-6 weeks of age, you may start noticing distinct differences in feather growth between males and females. Male chicks, or roosters, typically exhibit faster and more prominent feather growth, especially in their neck and tail areas. In contrast, female chicks, or hens, generally have smoother, slower feather development.

  1. Study Comb and Wattles:

The comb and wattles are fleshy protuberances on top of a chicken’s head and under its chin, respectively. These characteristics are more prominent in roosters compared to hens. Male chicks will develop larger, redder combs and wattles at an earlier age, while female chicks tend to have smaller and paler ones.

  1. Observe Leg Development:

Examining the legs of baby chicks can also provide valuable clues. Roosters often have thicker, more muscular legs compared to hens. Additionally, male chicks may exhibit a pinkish tint to their leg color, while hens usually have lighter, yellowish legs.

  1. Pay Attention to Behavior:

Roosters and hens can display distinct behavioral differences even at a young age. Male chicks, even as babies, may become more assertive, trying to establish their dominance by pecking and puffing up their feathers. On the other hand, female chicks tend to be more docile and cooperative within the flock.

  1. Wing Feather Development:

Examining the primary wing feathers of baby chicks can also help in determining their gender. Male chicks often have longer wing feathers, while female chicks’ wings may appear shorter and rounder.

  1. Vent Sexing (Professional Method):

For those who want a more accurate determination and have access to experienced poultry handlers, vent sexing is a reliable method. It involves inspecting the genital area of the chick, where a trained professional can identify subtle differences in male and female anatomy.

  1. Wait for Secondary Sexual Characteristics:

As your chicks grow older, secondary sexual characteristics will become more apparent. Roosters will develop larger combs and wattles, long, pointed saddle feathers, and sickle feathers in their tail. Hens, on the other hand, will have smaller, more rounded combs and wattles and will lack the elaborate tail feathering seen in roosters.


Sexing baby chicks can be both a challenging and exciting aspect of raising poultry. By observing feather development, comb and wattle size, leg development, behavior, and wing feather patterns, you can make an educated guess about the gender of your baby chicks. However, remember that some chicken breeds might be harder to sex than others, and mistakes can happen, especially when chicks are very young. As they mature, their gender will become more evident with the development of secondary sexual characteristics. Enjoy the process of raising your baby chicks and watching them grow into beautiful roosters and hens that will become an integral part of your flock. Happy Chickening!
