In the Brooder
I have never heard of this before either, and may be waaay off with this thought, but is there any possibility that it could basically be sort of like a prolapse of the esophagus when he went to start trying to crow?? I am hoping someone with more knowledge of the anatomy will chime in because I really have no idea. Maybe they can say if that is even a remote possibility. I am very sorry for your loss.
