I have posted pictures of our first coop. I came up with the design by looking through all the coops on here It's 4x6. I have to finish the nesting boxes and put on the roof. I plan on using metal roofing recycled from my neighbors barn roof. We live in the northeast and have a concern about the winter months. I was thinking about insulating it with the foam insulation and covering thatwith 1/4 plywood so they don't peck at it. My wife is choosing the exteriors colors.
