I'm not too sure how old my chicken is but she was very young when we got her, I am guessing she might be some where from 5-10 weeks old? I have just noticed over the past couple of days that she has been making some different sounds, it almost sounds like a croaky lower toned sound. My 2 year old boy thought there was a duck in our garden. I also noticed that she's been staying in the same spot for longer periods of time, where as a little while ago she would be every where in our garden. Does this kind of behavior have anything to do with her readiness to lay eggs? or is this a common development of all chickens?
