I've got a mean girl, tips to change her attitude please. Would like to avoid the pot, but have considered it.

This is Ruby. I got her when she was about 5 months from a place that had way too many roos (they have since thinned out their roosters)

So I am thinking it's bc she was in self defense mode a lot

Her back is better and I have separated her a few times. But maybe not for long enough? Just a few hours at a time.

She almost immediately goes right back and charges and pecks the other ladies. Its making all my girls somewhat mean.

Please give me detailed instructions on how to break her of this.

Length of time, how far from the other girls, etc.

Id really like to keep her.

Once I get a hold of her, shes relatively chill. Should I hold her more? Carry her around?

Please help!
