Hello! We are finishing up construction of our new coop and need to put in the ventilation. We live in Albuquerque where temperatures vary quite a bit. Winter lows are in the teens. Humidity also varies currently is 63%. Summer highs are in the 90s. I built the coop without plans and am starting to regret it. The height of the coop is roughly 3 foot on the back side and 4 foot on the front. I put a roost about 1 foot off the ground. i imagine when they perch on the 1 foot high roost that there isn't much room left above them for ventilation. I imagine that they would be practically looking out the ventilation! I could use the other two sides (one faces run/one is outside door) because they have a side that reaches the higher wall.
