One of my girls just started laying the other day, quite a while after the others. She used to be quiet and just follow the other 5 about. There were two other girls who were a bit mouthy but not too bad. Since she started laying she never shuts up while I am around. I tried giving them treats when she was bawking but she wasn't really interested. She jumps up onto a perch in the run, looks directly at me and BAWK BAWK BAWK with her mouth wide open. What's her problem?
