Based on the Polish I raised this year and how mine turned out, I would say pullet on the right and cockerel on the left by the shape of the crests.
Our pullets faces are deffinately covered more, and the cockerels shows more. Looks like a pair to me for sure.
Also, my pullet developed her crest sooner then our cockerels, which I've heard is common. Did you notice if one or the other of yours developed sooner?
