My beautiful Rosecomb rooster's tail is slowly falling out. He loses about 2 large tail feathers a day. Not that you can really tell, he has so many, but I'm worried. Is his tail just molting? He's not losing feathers anywhere else. Actually, I've had another older rooster who lost all his tail feathers at once and grew them back quickly, but this Rosecomb is losing them slowly. Plz help!
