The Coop is a type of farm building purchasable and upgradable from Robin at the Carpenter's Shop. It takes three days to build, and two days to upgrade.
The coop can store chickens, ducks, rabbits, and dinosaurs.
The total cost of a Deluxe Coop, built from scratch, is 34,000g, Wood (1200) and Stone (450) (Or, if all wood and stone are bought from Robin, 55,000g).
The Deluxe Coop features an Autofeed System; hay from your silos will be automatically distributed. (You can still let the animals feed on grass outside, and the hay will not be eaten.)
Coop Animals may be stuck outside at night if the coop doors are closed. The conditions for this are not clear (see the Barn Talk page). If an animal is stuck outside the coop at night, the next day his/her mood will be "grumpy." Animals stuck outside are also subject to Wild Animal Attacks.
