Hello. I am completely new and, although I have a thousand questions, my first is that my new rooster, Henry (Rhode Island Red) appears "healthy", but he breathes through his mouth and is loud when he does it. He seems to tilt his head just slightly and shakes it alot. He appears otherwise healthy. Does not have a cough that I noticed. I inspected his eyes, beak, nostrils and all seem bright and shiny. There is a little crud in his nostrils, but no more than any other chicken I ahve checked so far. He doesn't appear to be in distress when he is breathing, just very loudly through his mouth and his chest puffs out with each inhalation. Shiny feathers, eats fine, etc. etc. Anyone have any CLUE????
