Not sure if you guys are meaning the same as me when you say "buff" ducks? My buffs were buff Orpington ducks. In the pics it looks like a blueish sheen on their backs my buffs never had that. Also the drake has some of the white ring on neck. My buff drakes never had that.
I do still have some mixes from my buff drakes over mallard hens. They look more like the OPs.

Yes....Orpington....Some do and have a blue or lilac colour...

My drake has the white collar on his neck and his head is grey the feathers are light buff and white the ducks have dark tan.

Here is a pic of a pack of buff orp drakes I had. At least in pics mine does look like yours color wise. As you can see though no white on necks.

Wow, he looks just like them but they don't have a collar.

Buff ducks. One male and two females. Should start laying between 5-7 months on a proper diet

First post....2 hens, 1 drake.
Buff Orpingtons.
Buff would be the color.
I have quite a few of them.
I also have a trio of buff Orpington crested ducks.
