Chicks are baby chickens! Baby chickens are called chicks, 3 month old females are called pullets (until they start laying eggs around 6 months), adult females who lay eggs are hens, and males are roosters, co*cks, or co*ckerels.
After a mother hen lays an egg, she sits on it for almost 24 hours a day until it hatches. After 21 days of incubation, a baby chick will hatch by pecking it's way out of the egg! These little peeping fluff balls grow very quickly and double in size in their first two weeks. They start growing adult feathers almost immediately, they reach full size in 20 weeks, and can lay eggs of their own at only 6 months old!
