I live in Oregon, Portland and it doesn't snow usually. We got a few inches yesterday and they won't even leave the coop. We even have a run for them, which is covered, but it was windy so it blew a bit of snow in, and they're just cold I think. It's 20 degrees, is that okay for them? Is there anything I can do? And also, since their water keeps freezing, and I have to keep getting fresh... Are they smart enough to drink out of a bowl when they're used to chicken waterers? I'm worried they won't know it's water. I know chickens aren't the smartest animal in the world... Any other helpful advice about chickens in the cold?
