I got a major deal on a shed, if I choose to take them up on it. It's a tough shed, 8X8, barn style, with a corrugated metal roof. So... in the summer in the Sierra Foothills, will this roof cause a heat problem in the coop? There are vents, and the guy said he'd cut a window in for me too. I'm not worried about air circulation, but I am thinking that the roof will be hot. Do the folks here who have metal roofed coops insulate? If so, what material do you use? I don't want to go out one morning to find a bunch of hens with pink insulation hanging from their beaks!
