He looks just like my serama roos. His breast redness is from him being inactive and laying on it too much. Softer bedding should help til you can get the extra weight off him . No treats, no corn as was said and I never thought to try aspirin but its worth a shot ! Good idea @MissChick@dee

Agree sounds like circulation, hope he gets better 
His comb is darker than ever and he's very thin. I haven't been home in a few days, so I'm worried about how poor guy's doing.
Sorry to hear of his passing
