Chick Nursery. This is the second coop I built myself. The design is very airy on top to allow airflow during the hot California summers. Although I originally used this coop for newborn through fully mature egg layers with free range access daily, I currently use it as a nursery for youngsters. Inside, I have it divided with wire so that new babies are on the right and older babies on the left. There are two doors behind the coop as well.
