My coop is a storage barn we were not using so we turned it into a coop. Took out the windows replace them with chicken wire. We added shelves for nests for the chickens and put beams across the barn for them to sleep on. Then we also built a spot and caged it in with heating lamps for the babies. Its huge and the chickens love it and and it keeps the bad animals out. We don't have a fence around it cause we have lots of land and we let them roam free during the day and they all wait for us by the doors to be put up for the night.
