I have a four chicks somewhere in between five and six weeks old, and three pullets that are eight months old. Right now, I have them in two runs (chick's run is slightly larger) with a deer netting door separating them in the middle. I'm not sure how to continue with the integrating process, because although the older hens don't pay much heed to the chicks for the most part, when I put the two groups of pullets together, the hens bully the younger ones quite a bit; keeping them away from the feed, chasing them, pecking them, etc.. I have the "see each other but no contact" part down, and have for nearly three weeks now, but the older hens just aren't accepting the little ones and I can't keep them separated for too much longer. Suggestions?
