So i went to feed my chickens this morning and strange he wasnt the 1st one out. Then i saw the big black boy. But walking slow. Once he cleared the entry he kept his head down. I touched his behind to see what was wrong and his head went up to normal. So i started my feeding frenzy. I looked back and there he was again. Almost looking at his claws. My dad made some cuts on his combs. He believes that he has too much blood there. I dont have any hopes for him. But just wanted to share and learn about this. Is it comon? Could it be prevented?
