My Dorking hen is doing the hide in the corner, don't eat don't drink thing. I gave them super warm water, plenty of grain and no one else is acting poorly. I think the hatchery Dorkings are not up for NH winters. Don't think badly of me, but I am not bringing her in the house to try to warm her up. I can't breed chickens that can't handle our weather. I put the water dish and some grain where she can reach it, she's in a sunny spot and let's hope she can snap out of it. Otherwise we'll just be breeding Dominiques and Cornishes, all of whom currently look perfectly content (and feisty, for the Cornish roo!) despite the cold.
