I have a 3-year-old silkie rooster. I have had him separated from other roosters because a storm damaged our coop and he is special to me. Today I let him out for a little bit while we were fixing the coop and he decided to fight with some of the roosters. He now has some gurgling and blood in his mouth. I checked his down his throat with a flashlight for any trauma there and I couldn't find anything. My best guess is he possibly broke a blood vessel in his trachea or lungs. He is separated again. Is there any treatments or supportive care I could do? There are no vets in my area that will treat chickens.
