That bird is really pretty! I don't think the hens are blues; they def. have the lavender. They are much much lighter than the blue male. I posted pics a while back on the lav orp thread. At that time, I knew one had a slightly darker head but the one with the darker patterns on her back just recently started showing. (Or I just noticed.) I guess maybe it is just b/c they are early generation birds. Or maybe she got something on her back
She runs every time I get near her so I could be wrong about it being her feather color ... what a dummy I would feel like then. But one definitely has a dark head.
