My roo has a pretty severe case of frostbite for about a month now. I brought him in yesterday when we found him bloodied by the flock. While I was cleaning him I noticed his wattles are extremely swollen on one side. There is very little frostbite on his wattles, but they are both warm and swollen. The left one is much larger and warmer than the other. Is this infection? What do I do for him? He's shaking his head a lot but seems to be eating and drinking. I've been putting neosporin on him, but not sure what else to do at this point. This poor guy has had a really rough winter and I just want him to get better and back to his flock.
