There are more chickens in the world than any other bird.
Baby chickens are chicks. Young female chickens are pullets. Once they lay eggs they are called hens.
The chicken is a subspecies of the red junglefowl, a member of the pheasant family that is native to Asia.
Chickens were probably first domesticated for cockfights, not as food.
Chickens can fly high enough and long enough to get over a fence or into a tree.
Chickens are omnivores and eat everything from seeds to insects and even mice and reptiles.
