We live in a very, very hot part of the country. These are my first chickens. My roo seems to wheeze a little bit when he breathes with his mouth open. Can it just be this hot, hot dry weather? Other than that he seems fine, is eating, etc. He does keep his wings a little away from his body. I'm thinking that's to help keep cooler. I also saw all three of them in little dirt holes they had dug the other day. To stay cooler? Thanks!
