Our coop will be 5 x 10 with the 5' sides facing north and south (run to the south). I am planning windows on the north and south ends but should I also put windows on the east and west sides? There are no trees there so no shade around the coop. We have grain bins to the east but I am not sure if they would shade it in the morning or not. I worried that just two windows (plus 6" by full length vents up top on all 4 sides) would not let in enough light and/or air in the summer but would it on this size coop? I'm going to the restore shop tomorrow and hoping to find some windows.
