Can you have to much of a good thing? Our coop will have a lot of ventilation according to my current plans. The front door will be screened, with a one foot wide screened area on the side and almost two feet of screen above the door frame. Two sides of the coop will be screen for aprox 3 ft on top, both of these sides are on the interior of the barn. (Converting barn stall.) The back door will have plywood up to 3 ft and a glass window above that, with 2 ft of screen above the door frame. I'm not worried about having enough ventilation. I'm more concerned with having to much. I am locating the nest boxes and a set of roosts in the corner that is the most protected from the elements, and another set of roosts on the other side. Any comments?
