First of all I am in Alaska and it's been warmer in the last month than previously. I have 6 chickens all hatched last June and they have been thriving. I get 4-6 eggs a day even though it's dark and winter here. But for about 5 days now I've notice one of my chickens has her feathers fluffed up like she is very cold and she is just standing by the side not active. Then yesterday I found her in the coop while all the other chickens are out. She was on the perch but she is very slow to react. I brought her into the arctic porch where I have a large dog crate with straw and food. She just stands in there. I don't see her eating or drinking or moving much at all. It's warmer in the porch and I thought maybe she needs some warmth and now this morning she is laying with her eyes closed and I can barely tell that she is alive. I tried giving her water with an eye dropper but she convulsed and couldn't breed until I held her upside down and let the water flow back out.
