A chicken coop is a building where chickens are kept on a farm or homestead.

The inside of the chicken coop normally consists of several nesting boxes just large enough for the chickens to sit in while laying their eggs as well as perches for the chickens to use while sleeping. Often the floor of the chicken coop is covered with a material, such as straw or wood chips, to contain the chicken waste and to allow easier cleanup of the chicken coop. Sometimes the chicken coop contains feeding and watering devices for the chickens, but these may also be kept outside of the chicken coop. Most have some kind of ventilation to help air out any odors that may occur.
