So this is my first winter raising chickens. I have to say it has been stressful. I have 6 barred rock hens that are 9 months old. Since I live in Maine the winters are very harsh. I have coop and a run for them but since it has been so cold they have lived primary in the barn. I came home the other day and one of my chickens had blood all over her head. Apparently she had gotten frost bite and the other chickens have been pecking her! I removed her and put her into a large dog kennel until she heals..... My questions are...is that ok? How long should I wait to put her back? She seems so unhappy in it. What can I do for my chickens so they aren't so miserable living in the barn?
