I keep going back and forth on this one. I have a 8 wk old blue Marans that is definitely a cockerel - he has a bigger comb than the one pictured, copper starting to show on his wings and he is starting to crow. This Black definitely has a developed comb (not as much as the other) and is a bit of a jerk, but no copper on the wings and holds itself more like a hen, in my opinion.
