It's been over a month now and my older Production Red keeps chasing my younger GLW pullet. When they free range it's not as bad as it was. Now it's rare and more like a bluff charge as a reminder to the younger bird that she's still in charge. My concern now is whenever they get into an area where the younger one can't get away, like the run. The older bird knows it and goes right after her. She usually corners her causing the younger one to get low and put her head into the corner of the run. And then the older one pecks and scratches at her non stop. I still have them seperated unless they are free ranging. Another concern I have is winter. Right now I have a divider in the coop. And every morning before work I take the young one out and put her in a small dog kennel in my shed. I've been thinking about building a small coop just for her. Any thoughts or suggestions?
