What breed are my ducks??!!!

[Americano Blue]

I have two very sweet ducks but I don't know what breed

. they have red skin around there eyes like a chicken and are black and white. all I know about the breed is they don't get along with any other kind of duck and they are completely quiet and when they do make a noise its soft and sounds more like a dove mixed with a hen. I don't have pictures. PLEASE HELP THE NEWBIE!!

They sound like Muscovies. Do they perhaps look like this?

yeah

(except their face is less creepy and their beaks have a tad more black) the gal I got them from found the pair walking down the street and didn't know what breed.
