Did you build all that? Very good though either way. We're using a simple metal gardening shed that was already in the backyard when we moved here. Mom added roosts and nest boxes on the inside. Very warm at night but noisy when it rains.We are in the High Desert @ 3,000' Our coop is 10 x 12 and built with windows on all four sides covered with chicken wire. The wind prevails from the East to West in the winter in my area. The North and South windows (3'x6') tilt inward to deter the chickens from trying to jump up onto them the other two (2'x2') just have plywood inserts that I remove in the warm season. The chickens have both indoor and outdoor automatic waterers and there are three 150W ceramic heaters above the roosts on a thermostat that is set for 40*. The droppings pit has chicken wire top and a hinged front for east mucking out. I keep +/- 30 hens and eight nest boxes works well. I also have about 30ft of roosting space.
