Today will be a test. I’ve decided to lock the flock in the coop for the day. The temps are still close to 0 (zero) but luckily the wind has dropped off a little. I surely will check on them throughout the day make sure all is well. It’s a spacious coop, but they’ve never had to all stay in there at once (expect at night when they are all sleeping) I don’t see much choice other than let them get frostbite and lose their combs and toes. They’ll soon forget this and spring will be here
