We have three female bragg's mountain orpingtons that are 5 months old, and are healthy, but our 2 month old cockerel is wheezing, making a sound when he exhales and at the back of his mouth where the tongue ends there is yellow. You know a chicken's tongue will look weird if you look far enough back. I don't see swelling, and I hope that it's not wet pox because we can't lose him. I hope we don't, but if we do I said that I will make a post asking for an adult rooster. Please tell me your opinions on what he could have, and help me treat him.
