Pullet or cockerel?

[PerkieChick]

I bought 2 buff orpingtons from a hatchery, hatched May 4th. They are vent sexed as pullets. They look very different from each other, growing feathers at a different rate, and I'm thinking one is actually a cockerel. I know they are pretty young to know for sure, but I'd like an opinion. I think chicken #2 is a cockerel....thanks in advance.

Too early to tell and Buff Orpingtons can't be wing-sexed.
