A single chicken will not thrive in a solitary existence. Like other social birds, chickens like to eat and forage, roost and dust-bathe together. Unlike most other birds, they will lay eggs in common nests and often raise chicks communally. If you can't keep more than one chicken, you should consider another pet.

Healthy hens are able to lay an egg about once a day, but may occasionally skip a day.
