I purchased a man's coop with his 6 mo. old laying hens yesterday. It is not insulated or heated but there is a heated waterer and the long lights that run the lenght of the coop. I live in Utah and it is cold today. Is there somehow I can make it warmer by tonight for these chickens? Here are pics . There is a vent on both sides at the top that runs the length of the coop and there is an opening on both sides about 2 inches around the mid section of the coop. Coop is plywood. Thanks so much!!!
