Is it a bad idea to have roost rails near a window we plan to keep open? (Screened with hardware cloth, of course.) We live in a moderate climate — nighttime lows are between 40 and 60 degrees. We're converting a playhouse in a narrow spot in our yard into a coop, and I'm trying to fit everything in around the current structure. The opening into the secure run will stay open, plus there are three 18"x24" windows, triangular openings at the top of the two short walls, and a 1" open strip along the tops of the long walls. I'm trying to decide how many need shutters. It's a narrow spot without much room for opening and closing windows. I couldn't find an answer browsing the forums, but if I overlooked a thread, please point me in the right direction. Thanks for any tips!
