aggressive barred rock 2 month old chicken

[janet9462]

I was raised with farm animals including chickens, we just threw corn out and let them run free. I am now older trying
my hand at back yard raising in a small area where I must keep them penned up with a fenced in run area . I bought a barred rock (we always called them dominecker) she is aggressive toward the others but only when released in the run pen? anyone know why? My other 3 chickens are a california white hen and 2 brahmas, all about same age and size.

How old?
How long have they been together?

She could just be head hen and is schooling the others to that fact.
As long as she is not chasing them down, pinning them and drawing blood, I'd just let them work it out.

They are about 3-4 months no she is not really chasing them she just flogs at them. They are going back at her. I think it is more the bossy hen thing now. Thank You for the feedback!
