One of our chickens, a white Leghorn, got a frost bitten comb. It was doing fine, but when I went out today, it was much worse. She had been bleeding on her feathers, and though the bleeding was over by the time I got out I could see she had bled a fair amount. Should I seperate her? We have an old bunny hutch that is insulated with plastic wrap, and stays very warm in the summer, but I am not sure if it would keep her warm enough at night. We are getting down to -5 at night this week. Otherwise we have a place we can put her in our garage, but I think she would stress out way too much. Also, is there anything I can put on her comb to help?
