I have two Columbian Wyandotte hens who have been in quarantine for two weeks. They seem fine. Right now they're in my husband's shop, which is a large 3-sided shed. They are in the back in a two-cage suite with a tarp over the back for a hidey-hole. It's going to be about 12 degrees tonight and tomorrow night so I'm wondering if I should move their cage into the coop. The hens are protected from wind in the shop and I know chickens take cold well, but it's just two of them.What do you think?
