Hello, Below is a picture of our coop and I wanted to get some advice on winter ventilation. I am not sure if this will be too drafty and any suggestions would be greatly appreciated. We are in Utah so we do get cold and windy winters. I added a 2" x 6" vent in the upper left hand side after this pic was taken and there is another vent at the same height on the inside of the covered run. Also, the back side has a vent just like the front of the coop as seen in the pic.
