I have built 2 coops in the last 5 years. The are easy to do. The first one was a 8x8, 8x16, and 8x10 closed in run. I went down to the Home Depot and purchased fence panels 6x8, 2x4s, 1x4s, tin for the roofing, sheet metal screws for the roofing and wood screws. The closed in run was a originally supposed to be used for an open carport, I just put chicken wire all around as the roof and sides.
