We got her from a feed store kind of far from our home. Our feed store we always go too wouldn't have chicks for another few days so we picked 3 up from another to try them out. The guy didn't know squat and I've heard mixed reviews about the place so I wouldn't be surprised if she is some sort of mutt.
Could be. I have raised a lot of barred rock and do not recall ever having one with white like this one.
