Hi, I live in the very North West of the pnw, and we have been getting temperatures like 30 F. I know that chickens can survive cold without help, but my concern is that when I was gone for Thanksgiving, we had our tractor parked right next to our house under an overhang for 4 days. In that time, the chickens shed quite a bit of down. They are parked under the overhang again tonight, and I put Christmas lights and a blanket over the run and house. There's 4 of em total, but sometimes they leave one out while huddling. I was wondering if I should use a heatlamp outside the coop to shine in, or maybe put one inside? Also, we are moving them into a permanent coop soon, out from beside the house, so do you think that they will be able to avoid frostbite? Any other tips about winterizing are welcome. It doesn't get super cold here, but just enough to make me worry.
