do I need to have any other sides open? The entire south side of the coop is going to be open, that's the way I've designed it. What I don't know is if I want the east and west sides open. The coop is going to be 16x8 (16 W->E, 8 N->S) The North side has to be closed because of my breeder pens. The West side faces the house. The East side faces a field that has either Wheat, Corn or soybeans depending on rotation, this year it's corn. We are in NC, very humid. Highs in Summer of 100 without heat index, lows in winter in teens during the night.
