Just out of curiosity, how long does the pecking order selection process last? My Aussies are approx 9 weeks old and still working on it. I think I did upset the balance by selling 3 out of 9 chicks. That whole next week was fervent chest bumping, neck flaring, and foot boxing. They do seem to be slowing down now though. Most of the altercations are just a little hackle raising and it's over.
