My husband was nice enough to improve the coop for the winter, boarding up the wire mesh areas. I told him we needed to keep 3-5" at the top of the boards open for vents. This is on 3 sides, as the 4th side is the box side anyway and completely wood. Well, here it is December in NH, and there is an icy wind, as usual. Cold is one thing, cold and windy is just about unbearable. I'm tired of feeling like any morning I will have to chip my hens out of the ice, so today I duct taped the vents. Forget it. It's too drafty. All day long the chickens free range and the door to the coop is wide open. But at night, that baby is getting closed up. If there's moisture, it will have to wait until morning. This is a confessional. I know the rule is vent, vent, vent. But it goes against all common sense when the wind is blowing into the coop. I can pull the duct tape off at any time once the icy wind is no longer an issue, say about March. I hope the coopmasters forgive me. I think my hens will thank me.
