This is a single bird with, what appears to be, a mean streak. If, by isolating her for a while, we are able to change her behavior so she (and all of the rest of the flock) can live harmoniously, I see nothing wrong with that.[/COLOR]
I agree. There are just mean hens out there, just like how there are nasty people. For me, my chickens are pets, so I am willing to do what it takes to help my flock. My chicken that has peepers....when she gets mean, I put them on, when she settles down I take them off. They are not always on her, in fact she hasn't had them on in about 2 months. They do help her calm down and stop pecking and jumping on the rest of my flock. As a "keeper" there are ways of helping and calming down a mixed flock.
