Still a cockerel, and mix breed. Where did you get him? He might be an ayam cemani cross, or some kind of fancy hatchery mix like the mystic onyx (which I say because I think I can see a crest)

Looks like a cockerel to me, I raised a bunch of cockerels and their combs were all prominent like this one. Pullets only tend to start showing comb growth at around 12 weeks. There are always anomalies though
