Hello all I am new to this site. I have come to back yard chickens for help on so many things but this is my first post. My husband and I decided to change to a larger coop. Its an 8x12 ft shed we had built. We figured the birds would winter better with space, and that it would be easier to manage and clean. It is vented on both ends near the pitch for cross ventilation. My husband insulated the inside with good insulation and hung plywood interior walls 6ft 6 inches. ceiling is open. Everything I have read has talked about proper ventilation and how important it is. Why is my coop 30 degrees with 80% humidity?? This is making me so nervous. I clean the coop just about everyday by scooping, so poo is not problem I do have feeder/waterer inside with a warmer I made from a cookie tin and lighting kit, to prevent water from freezing. I am really hoping my cheap tractor supply thermometer/humidity gauge is faulty. Any suggestion?
