Last night was a very cold night and my rooster got frostbite on his wattles as well as in between them. This morning they were very swollen and since then i have had him in the garage all day to keep warm.There is so much swelling that it is actually keeping his mouth open because it is so heavy. All my other chickens are fine because their combs and wattles are no where near as big as his. The swelling has not gone down at all today and it looks as though his wattles have even gotten a little more swollen during the day. How do I reduce the swelling? I'm worried that this will affect his breathing. I need some opinions please!! For the rest of the winter I definitely plan to keep him in the garage, I just want to know how I can help him right away because it his affecting his eating.
