Hello! I am new here. Today when I was feeding the chickens I noticed that my Rhode Island White was sitting down among the busy chickens. I picked her up and inspected her for injuries, as she wasn't moving. When I picked her up, I noticed she had a frozen foot! I rushed her inside and put her in a box to warm up. Her foot is now flexible and she is becoming increasingly more active. The only thing preventing my from putting her back in the coop (now with a heat lamp, the reason that it was missing before was because we had just gotten a new one and I was unaware of the temperatures) is that her "sisters" are pecking her. Aggressively. As an example, the moment I put her in with her sisters, one pecked her and she squawked in pain. I have brought her back inside. What do I do? I know that the pecking order needs to be reintroduced, but it's only been half of a day and they're already becoming aggressive towards her. Any help is appreciated. Thanks!
