I got this in a McMurray rainbow layer mix. It's nine weeks old now. It was being picked on and had a bare spot on it's back so I moved it into another cage with a tiny chicken of the same breed that was also picked on. Now I'm beginning to think it might be a roo. Why would a roo be picked on by a bunch of pullets, unless you think there could have been another roo in the cage. Thanks for any insight. I hope these pictures are ok. It was hard to take them because (s)he freaked out with the camera around.
