Is this a roo?

[mitchl-2000]

I got 6 baby female buff Orpington and one has started growing a very impressive comb and waddle.
Does this comb guarantee she is a he?

Yes, I would guess its a rooster

How old are they? I have 2 BO pullets about 6 wks and their combs are very light pink and small. I would say that's a cockerel!! Looks rooish too.

cockerel, indeed

Without a doubt.
