Great article. I have 3 hens in a 8x10 coup to sleep but free range all day. The double doors are open all day and I clean their poop (sand) every morning. There is a little window also And vents on each end that were made in the shed/coop. Since the double doors are open all day, is that enough ventilation? I shut the doors when they roost and I have a small dehumidifier inside. I’m a newbie, thanks.
