Went to a local bargain store got some pallets covered in plywood. They were used to deliver irrigation pumps. So no chemicals. I tured the plywood in and did 3 sides top and bottom. Used plywood on the last side to build the entrance door. Made 3 . 4x 8 side and one 4x4 frame. Put wire on the frames. Screwed them together, cut an entrance hole in the side of coop. Put the frame against it and now I have my setup. I have eight 3 month old Buff Orpingtons, and they like there home.
