My boyfriend and I are slowly working on our coop and are having some disagreements about how much ventilation is necessary. We live in central Virginia, where it gets very humid and fairly warm (pushing 100 several days, with the heat index quite a bit higher) in the summer, but then we get wacky stuff like those blizzards this past winter. Our original plan was to leave about a six inch gap under the roof, covered with fencing, to allow air flow. However, I'm starting to feel that's insufficient. Our AC has been out since July, and since trying to sleep in this humid awfulness, I can only imagine what it would feel like in this coop. Am I thinking that chickens are more temperature sensitive than they really are, or are we going to need more vent areas?
