About a week ago I went out to check on penned groups of chickens and found a young stag / cockerel housed with hens was not looking thrifty. I handled him to find he was very much underweight. I needed a bird to collect feces from so brought him in hoping he would be good for that purpose. He is now one of my house chickens. Indoors with quality nutrition he got thrifty quickly and is coming back in weight. What I have noticed is he seems to cough occasionally and does not put his head back over his back while sleeping. He even holds his neck extended where it slowly sinks down until he jerks it back up to about horizontal to repeat process. He also appears to have excess fluid in his crop when it is distended. He is not cropbound as crop empties normally.
