I have a question, my rooster recently had mystery bleeding on his comb and the blood stained his beautiful white feathers. Now he looks like he stuck the top of his head I a pile of wet dirt and it dried. He is a jersey giant white and very affectionate so picking him up will be no problem. He climbs in my lap in the yard and takes naps all the time. I want to wash his head. Is this possible? Will it hurt him?
