I’m getting close to finishing our first coop build and I wanted to get input on ventilation. Our coop has a window with hardware cloth on the front and back. I added a vent above the door on the front. I plan on adding hinged coverings for those two windows for hard rainy days and winter. I’m located in NC so we don’t get the bitter cold that northern states get. Should I add another vent on the back like the one on the front or would one be adequate? We have 7 bantams. Thanks ahead for any input.
