Thanks, everyone. Yorkshire, I will definitely check out all those links! My plan was to keep her with my Cemani since they are smaller than my meat birds and will be kept seperate. I have a fairly small flock, though, and my meat birds have had youngsters and much smaller hens in with them previously (and currently) with 0 problems.
I bought "her" from a friend, so I am considering going over to her house and pick out one more from the same group she was in...one that looks different, so that I hopefully at least get one hen.
