Over a month ago we had fowl pox run through the flock. I've seen particularly severe cases but never actually experienced anything this bad personally. We lost our smallest hen after days of hand feeding and watering her. She was the most severe and the first to show any symptoms. Everyone else seemed to get better after about two weeks and have returned to acting like their normal selves. All their feathers have come back in from their molt and they're all eating drinking fine. Except my rooster. He looks super poorly, feathers are extremely dull, his comb is dull and dry looking, and he hasn't crowed in going on 8 weeks now. He is also showing no interest in any of the hens which is unusual for him, especially towards his favorite hen that he's bonded to. He still gets excited and runs over to talk to me when he sees me and waits patiently for his treats but I just want to get him back to normal and feeling 100%. Anything I can give him or just give him more time? He was the one that was least affected throughout the fowl pox outbreak so I thought anyway. He's our special guy that everyone is really attached to so I really don't want to see anything happen to him. He is not showing any signs or symptoms suggesting any other kind of illness.
