I’ve read a lot about drafts... how crucial it is to avoid them if you live in a cold climate... Particularly, I read about not leaving anything open at floor level, because it will create a cross breeze with the roof vents and blow across the chickens from floor to ceiling. However... This is at odds with what I’ve read about a lot of people leaving the pop door open year-round. And now I’m confused. How does the open pop door factor into the drafts equation? Do people leave it open only in warm climates? For context - we get cold winters here, but like 20s-teens kind of cold, and even that isn’t daily. So not like Canada-level cold. The occasional blizzard. I’m planning a 5x7 partially insulated coop (floor and roof insulation only), 7 feet tall (sloping down to 6 feet), for 3-5 chickens. 4-inch tall vents 7 feet wide at the top of both long walls, so across from each other, and way above roost level. The roosts will be along one of the short walls, the pop door on the other side of the coop, by the opposite short wall. The run will be partially covered with plastic for the winter (certainly the area near the pop door, and the whole top and 2 sides. With all this in mind, do you think I can leave the pop door open in the winter?
