had to expand the original design to accomodate 3 generations of chicks I've hatched.120 square feet of ground space.6ft of height. Doorway in between so I can feed and clean the coop. Also the older chicken can be kepted in another area while dealing with the pullets and cockeroos escaping out of the brooder box.
nesting box on top can hold 7 hens at one time. Brooder underneath at age 4 weeks. Figure this way I can mix the new flock easier at age 8 weeks.
Original design. I use tarps on all sides to insulate them and as well keep them dry.
