What are my ducks?

[Lassi001]

I was told I was buying a hen and drake Mallard but now that I have them home I’m really thinking that may not be the case. What do you think? Mallards or Rouen and male/ female? They’re supposed to be juveniles which is what I wanted…

They are a pair but I'm thinking Rouens.
I've raised Mallards but not Rouens so I'll let someone else give their opinion but I think Rouen hens have two face stripes compared to the Mallards one.

I was thinking the one on the left is a Rouen too since it looks clear to me that there’s 2 stripes. But since the one on the right has 1 stripe I was thinking a Mallard but can’t decide if it’s male or female. Completely new to this though!
