My aunt wants me to take a hen of hers (plymouth rock I believe, about 3 years old) because her other hen died, and this one's all alone now. But she's had the hen in a coop with a heat lamp, which I don't have. I'm in Michigan, and it's been single digits lately, so I'm not planning on bringing her home yet since I'm worried she won't be able to adjust to the cold. Here's my question: should I wait until spring? Or is it enought to just wait until the highs are above freezing again? I've heard that chickens can die if the power goes out and they loose their heat source, which is one reason I've chosen to not use a heat lamp. Does anyone have any experience with this? thanks in advance!
