It's DaisyBuff here. I have 5 Rhode Island red chickens 11 months old. And a golden Buff Orpington Named Daisy 1 year. It has been getting in the teens at night 16 degrees last night. In the day Its about 25-40 degrees normally in the later 20s under freezing temps, should I lock them up in their coop at night with a heat lamp? According to the weather it's just going to get colder, and I know chickens can keep themselves warm, but I still don't know what I should do? I need some help. I also have a little quail named Alice that lives in a pen attached to chicken coop I'm worried about her to.
