Is it okay to hear a chickens breathing?

I don't know how to put this but the other night I was putting my flock to bed and well my Plymouth like I could hear her breathing. It was a little heavy I guess. I thought she was wheezing but I don't think that counts as wheezing. She seems fine and no sign of illness I don't think. Is it a normal thing???

If it is really hot outside then it would be normal but if it was cooler your chicken might have a respatory disease.
