My rooster has a large yellow lesion on his comb, and small yellow ones on his earlobe of the same side. (Best seen in the second photo.) He is also a bit lethargic, and stops crowing mid-crow as if he has a sore throat. He doesn't appear to have any other symptoms yet other than staying close under the light for warmth. (Note that he is a Golden Phoenix, and his earlobe is normally white with the pink tinge at the bottom.) We have had crazy weather over the last week with rain, ice storms, snowstorms and temps swinging from high 40's down to freezing like a yo yo. He has a little bit of mild frost-bite as seen top right of the first photo. He is such a nice guy. I would sure appreciate any help to figure out what this is, and what to treat him with. Thanks so much!
