I have an 8 month old Americauna hen(Emerald) who has been getting more and more aggressive with the other hens. 5 of my 10 are only 3 months old, and one is a roo. She leaves the older ones alone but really makes a point to pick on the younger ones. She doesn't rip out feathers, but she is a big bully. If I let them free roam she will see them in the distance and chase them down just to attack them, all the others would mind their own business, but now another is starting to pick up her behavior too. So I put Emerald in her own pen to think about her bad behavior. I want to bump her off her high horse. So how long til I can re-introduce her? I hear a week. But would 3 days do the trick?
