Today I let my 5 week old hens free range with the big girls. The young ones walked into the established girl's coop at one point and the big girls followed them in but were not irritated in the least. They didn't even do so much as give them a second glance. In fact, one of the 5 weekers charged the hen I thought was at the top of the pecking order. Do I dare let them roost together tonight?
