This is our first rooster and his first winter here in Wisconsin. I'm not sure if this is frostbite or not. We've only had a few below freezing days, the coop has been dry and ventilated well. But his waddles are purple and look swollen. He was hen raised so he is very cautious of us and I still haven't been able to pet him. So trying to catch him and bring him in the garage is not going to be an easy task. Any advise for what I can do for him?
