I've noticed in some of the threads on cold weather that some of you bring your birds in when it gets really cold. I know chickens can handle very low temperatures, but I do worry about my girls on cold nights. I'm wondering what y'all do with them when you bring them inside. Do you make a nest with a cardboard box and some hay or shavings? Do you put them in the bathtub with old towels? Do you have a little pen, or do they have the run of whatever room they're in? Do they settle right in and go to sleep when the room is dark or do they wander about or fuss? I'm in the Atlanta area. I have three hens who spend their nights in the "Saltbox" coop from mypetchicken.com. It's supposed to be in the low-mid-20s here tonight. I think they'll be okay, right? But we occasionally have nights in the teens, and I will be VERY tempted to provide warmer quarters for them on those nights. There's no electricity at my coop, plus I'm a bit fire-phobic, so a heat lamp isn't really an option. Thanks!
