Need help finding my ducks gender

[Anph4m]

We received two Muscovy ducks around 2-3 months ago. At first, we suspected that the black one was a hen and the white a drake. The white duck is considerably larger and has more of a caruncle but not as much as some drakes you see. It is also timid and gets bitten by the black one a lot. I also noticed it sat on the nest a few days ago.

Is this a large Muscovy hen or a young drake?

How old are they? I'd like to see a profile of the white bird, but I think it's a drake.

We bought them from some guy who knew a duck breeder, not much information was given but he told us it was a pair of hen and drake. They are laying eggs so most likely 28+ weeks if that helps.
