We're building a 8x12 coop/feed storage/tool shed (yeah, the tools will get about 6 square feet, and the rest will be for the birds!) and I want to insulate it. Could I stretch a sheet of plastic over the insulation for now to keep the birds out of it until I can get something more permanent up, or will the birds peck at that too? It's pretty thick, at least 10 mil, and I could run two layers if I need to. I have almost a whole box of the stuff. I also wondered what kind of latch you use on your pop doors. I'm going to set mine up so I can open them with the pull of a string from the no-bird section of the coop. Do you just tie a rope or chain and pull them up, then secure them at the top, then release them and the weight pulls them closed? I've done searches, but there are so many threads with info on pop doors, and I haven't found directions quite like I wanted to do. Better yet, is there a miracle latch that will keep the door shut at night, then hold the thing open, and can be operated from five feet away? I'm kidding, of course. I can't afford to buy three automatic doors, and I want to have the ability to split the coop for breeding next summer, so I need three doors, and I'll split the run a bit.
