My two roostgers feet are swollen and I have no idea why. There is no sign of bumble foot. We have been in single digits temps for five days. On the second day of the cold snap I noticed their feet were stiff and cold so I briught them into the house to warm up before they got frostbite. The next morning I noticed they had blisters on their feet that wernt there before. I putt blue kote on their feet and now their right foot are swollen and they keep that leg lifted. They will walk on them but when they aren standing still they raise their. The skin is peeling where the blisters were. They eat and drink fine. Please help I have no idea what to do. I'm worried about infection. We have no vets that do birds around me either.
