The pic of the brown one, pic 5 I think the close up of the head, is that the beginnings of a forked comb I see just above the cage bar? If so that speaks of polish deinately that and the mohawk crest going on. Polish mix? That is some pretty l;oose barring for a BR from everything I've seen but it definately looks roo-ish. Hmmmm run that one past Speckled Hen see what she says?
I am far from any kind of expert these are just things I see in the photos!
I think the brown one is really kewl no matter what it is!
