You definitely have at least one cockerel, no doubt. There is a difference in comb/wattle size, but still good sized even on the one with the smaller set. If their legs are the same size (hard to tell from the photos), then I suspect they are both cockerels. I have two younger Lav Orp cockerels, and one lagged a little behind the other for a couple of weeks, then caught up in terms of comb/wattle size and color (which is typical when you have two or more cockerels together). All this said, I have a mature Buff Orp hen whose comb and wattles would put most roos to shame! Orps are tough.
