My Polish White, TopHat, was sitting on top of an old rabbit hutch that we have in the pen for them to sit on. After All, this is Wisconsin. The temperature dropped to -23 at night and was -20 when we fed our two chickens. She was on the hut and didn't come down for feed, unusual but not uncommon. Don tossed bread and still she didn't come. We ran to gas station she was still in same spot. Then we ran to walmart and came back still not moved from spot. We went to get her off the hut and she could not move. We thought hot water but then thought of other bad things to happen. Fortuneatly she wasn't frozen down too hard. She did lose a few feathers. I brought her in the house to warm up. After a couple hours, we put her back in the pen and I could definately feel a very improved body heat temperature for her. I am wondering if there is a safer way to unstick chickens if they get frozen in a spot. I hope it doesn't happen again but we will be looking at -50 degree wind chills in the next few days. They live in a dog igloo with lots of dry alfalfa for bedding and we add more as it gets "stomped down". My two chickens will be 2 years old in April.
