My chickens are 26 weeks old, laying like champions, friendly and social, eating well, look and act very healthy. What bothers me is the noises they make. They all sing the egg song and occasionally one will squawk when they have a little argument or if something's wrong (like once the door to the run blew shut, and one of my girls couldn't get back in when she was ready for bed). The rest of the time they make these noises that sound...sad, somehow. One of my girls honks like a goose. My experience with chickens is limited to these chickens, so my expectation may be skewed by the "cluck cluck cluck" of cartoon chickens...lol...but it worries me to hear them sounding so miserable when I can't see that anything is wrong. Any thoughts on this? Thanks!
