Just my 4penneth, but as we can´t see any saddle feathers (the light cockerel´s head being in the way), I´d say this looks very like a pullet. Maybe Barred Rock x Brahma? I used to have barred rocks, and the females would often have quite red wattles etc, but the one easy difference is that the females have a little less white on them (finer barring). Don´t go by the tail feathers, lots of young pullets have odd tails at first.
s this the same one that´s in the avatar? That looks to be pullet to me.
