My pullets Are all 13 weeks, and they look like your other Buff Orpingtons. I agree, hesitantly, with pullet, because of the feathering. Like others said, the comb and wattles are hard to ignore. Maybe your hen identifies as a rooster.
This is my 20 week BO rooster, and the feathering is more noticeable.
