Cockeral or pullet?

[kychickenz]

I've got a four month old Lavender Orp that we bought from a farm as a straight run and I'm starting to question it's gender. So far it stands taller and is broader than any of our other girls including our two EE's-problem is "it" hasn't started trying to crow nor have I noticed it trying to mount any of our other chickens that have started laying although it is considerably more aggressive than the others, what do you guys think?

I was able to tell my orpington was a cockeral at 1 month - I would think you'd be able to tell by now. 'Plus, her comb/wattle is to small for a cockeral. They'd be way bigger by this time. So my vote is pullet.

I am not the best with orps, but at that age I would cofidently say that is a pullet
