I have one chicken that is being mean to the new chickens and they've all been together for 3 weeks. this one chicken is a problem. I separated her, but she can still see them and stuff. she is in the old run and they're in the new run. the new run is completely around the old one. Now, will she never get it through her head to be nice because she can still see them through the fence? do I need to really separate her like, in my basement for a week type deal? because after nearly 3 weeks of her being in there, she's still going after them like a man woman the other day when I went in there and she snuck out.
