I've got 6 RIRs. The dominant one started laying about 6 weeks ago. She doesn't make much noise at all... just a little grumbling. Number 2 hen started laying about a week ago and is very loud... Before, during and after laying. The strange part is, she won't let anyone else in the coop while she's laying. If she sees another hen coming up the ramp she promptly runs them off. All the others have learned not to enter the coop while she's laying. I'm not new to chickens but never have encountered this behavior before. Anyone else?
