Duck Identification

Hello,

I moved recently and there were 2 ducks on the property that the original owner had 10 of, but there were only 2 left. A male/female pair that went everywhere together.
Unfortunately the female recently died, so I'm looking for some new friends for the guy in the attached pictures.
The neighbors say they're mallard that have had their wings clipped so they'd stay on the property, but this guy is an awfully large mallard
Easily 2x the size of my chickens. I'm thinking he might be a hybrid of some sort?
Anyway, I want to see if I can get him ID'd to get him some new friends close to his size etc.

Probably Rouen, though it's interesting he hasn't got a collar.  He's probably not pure bred.  Some Aylesbury ladies would be nice for him.

Hey Hester!

That was my thought as well, but like you said, no collar and the dark brown on his chest is very minimal.
I can find Rouens easy enough. So I think that's my best bet at this point.

I couldn't find any pictures like his. So I was hoping some one here could help.
The Rouens at the hatchery are 5-7 lbs rather than the 9-10. So I think they should fit in well with him.
