I just purchased a coop with 6 mo. old laying hens last night. I think it needs some sort of insulation. Is there something I can do for the hens by tonight? I live in Utah and it is cold right now. The coop is plywood. It has eight foot long lights running on the ceiling of the coop. It has eight foot vents on both sides of the top. It has another 2 inch opening running mid section of the coop. Seems like it would let in too much cold and there is not insulation. I don't know what to do. Here are the pics of the coop.
