The chicken pen coop is a mix of a pen and a coop. The pen allows the chickens to have a place to stretch and search for food while the coop allows easy access for nesting and roosting. Depending on the space available as well as the number of chickens, chicken pen coops can be made in numerous designs. The material is mostly wood with the pen being a wire mesh. For the safety of the chickens, the pen should be well fenced to keep out predators while the coop should be easy to clean and well ventilated
