Truthfully I could go either way, the comb doesn't look that big to me do you have an overview body shot? Often the males feather in more slowly on the body under the wings. Is it feathering in at the same rate as the others? If the feathering rate is the same I would guess pullet. But just to be sure...
...I would wait a couple of weeks and repost, Eventually it will be clear, I am still trying to figure out a couple of mine also.
I am leaning towards cockerel, wait a few weeks to be sure though. And just because it is black and white does not make it a rooster. I have had and know many people have Black and white hens, it is like sterotyping chicken colors!
