It looks like it has some barred breed in it. It somewhat looks like my cream legbar rooster, my boy have the crest up at the top too. Yours looks a lot darker though. So maybe some type of legbar? I didn't get any females out of that hatch, but I believe the females are darker. The boys combs were HUGE by week 3 though and I have observed that some chickens with straight combs seem to develop combs and wattles earlier than other comb types. That's just my opinion, others may disagree. The only time I have guessed wrong with girls and boys are with straight combs.
