Buff Brahama: hen or roo

[afre13]

I recently bought two buff brahamas from Tractor Supply and I'm trying to figure out if one is a hen or roo. Can you tell?

I cannot tell in those photos, but I notice that you posted this a while ago. By this time, it might have become obvious to you, or you could post updated photos to see if we can figure it out now that the chick is older.
