I accidentally got locked in my chicken coop last night (funny story). I was in there for about 35 mins waiting for my spouse or children to realize I was missing. While being in there I was able to hear my rooster breathing. He seemed to breath louder than the hens do. I would not say he was struggling to breath, or breathing heavily, just more loudly. This is my first time raising chickens so I just wanted to check to see if there was any insight on weather this was normal or not. He is otherwise healthy, eats fine, started crowing a couple weeks ago. I cant say how long this has been going on because when Im normally with them its not quiet outside so I don't normally have the ability to hear the quieter sounds.
