Chickens are omnivorous, eating a wide variety of plant and animal material. They typically eat insects, seeds, fruits, and other small animals.

Chickens are social animals and live in groups. They have a pecking order and communicate with one another using a variety of vocalizations.

The domestic chicken is thought to have been domesticated from the red junglefowl, a tropical bird that ranges across much of Southeast Asia and parts of South Asia. The red junglefowl were first domesticated in India, and the domesticated chicken subsequently spread to other parts of the world.

Chickens are kept by humans around the world and are used for their meat and eggs. In some cultures, chickens are also kept as pets.
