We're building an addition and I want to make sure it's got plenty of ventilation. The existing coop only has the walk door (which we keep open now but in the future we won't be able to) plus a window on the other end, plus the pop door. We'll be adding vents to the existing coop on one side where the nest boxes are now (these will not be used as nest boxes) and want to incorporate as much ventilation as possible in the new addition.
