Well, change of plans. I originally wanted to put a Clear corrugated plastic roof on my coop but my boyfriend thinks it's over kill since the coop is already INSIDE the garage. So what should I do for the roof? Should I just place some 2x4s across it and screw a piece of plywood to them? I should probly insulate the roof...how do I put insulation in the roofing? Do I sandwich it between plywood...? ( I live in Michigan which has cold looooooonnnnng winters, and the garage is unfinished, no insulation) The roof doesn't need to be weather proof since has the garage roof above it. The coop is only 4x6 ft This is what my (unfinished coop) looks like to give you an idea. Thank you!
