I am in south GA. I have two hoop coops. I am building my first coop that is not a hoop coop. My skills are limited. If I have two doors and one large window covered with hardware cloth, will that be enough ventilation? The coop is 4 x8 raised 30 inches. It is 52" high. The doors with be boarded when it gets cold. Probably leave the window open for most of the year.
