That front of the coop is facing north and back is facing south. I actually have gable vents and some other venting material. Soffetts all around, Windows on the sides that are permanent openings now and gable vents. If that's not enough by God then I give up. Thanks for the input. The coop has a solid floor, I've been thinking about replacing with hardware cloth. Keep the floor free of hay in summer except nesting boxes. In winter I'll throw straw on the floor for a little insulation. Thanks so much for all replies.
