Please help sexing our Rouen ducks

[crownsparkles]

These ducks are 7 weeks old. We’re still not sure what we have, males or females - is that big beautiful one even a Rouen?

One of the little ones with the yellow bill does quack so that helps

Thank you for any clues!!

1 male, 2 females.
None of these are Rouens. The two little ones are Mallards, and the big, handsome boy looks to be a Silver Appleyard.

I was going to say the same thing!
