Below are two pics of my rooster, one of his comb and wattles a normal red color and the other is what they look like now. He has been this way for several weeks now. He acts a little depressed but he is still eating and drinking and breeding hens, just with less energy. His poop looks normal and no other chickens are like this. What could have caused his comb and wattles to become so pale? My first thought is he is severely anemic but what would have caused that? Any help will be greatly appreciated.
