Sometimes my hens groom the roosters. The rooster stands there while the hens pick stuff off him. The rooster seems to enjoy it, and often close their eyes, and it looks more like affection to me.only one is older than him (she is 3 yrs) he is a year and a half old. 1 is the same age and the others are 9 months old. I think he is being beat up by the younger girls! maybe that is the reason why he has gone coockoo! they still pick on him some! others say have said they've been pulling his feathers so yeah....
You are better off with a gentle roosters like him. Most of what I see is frostbite. He has a huge comb and will lose some of it. The feather lose could be from pecking or it could be from molting. Some of my birds are still molting, it has been a weird molting year.
