We repurposed an old hog shed into our coop. Unfortunately the small chicken doors are located on the north side. Today it's snowing and blowing and the wind is blowing snow into the coop. I'm contemplating putting heavy plastic over the doors to slow down the wind and keep snow, rain out. Will chickens learn to go in and out of the door with plastic over it? Thanks for any advice or tips to keep it dry and warmer in my coop!
