I have a small coop 4x4 for 6 hens. Slanted roof vented above their roose (close to their heads) and on the opposite wall. It's driving me crazy making sure they will be ok, we live in Nova Scotia and it can get quite cold here, lots of windchill factors. the coop is insulated but no electricity. Golden coments, I clean their poop everymorning, the coop is dry inside, just worried when it gets really cold. I'm having a hard time keeping draft out and making sure they are ventilated? Anyone else with this dilema? I will try to get some pictures on here to show.
