Easter Eggers tend to show a lot of variance- they are not a true breed and don't have a standard of perfection. They do usually have pea combs (yours has a straight comb) and green legs, can't see legs on your bird.
It doesn't show red in the comb but, none the less I think that is a lot of comb for only 8 weeks old. If it starts to redden and enlarge soon, I would say it's a cockerel. Otherwise I would say pullet at this point in time.
