What breed are these black and white ducks?.

I was told they were Muscovy, but they do not appear to be. For a while i just thought it took a while for them to develop that gnarly look. I also just hatched the ducklings in the pic and they hatched on day 24. The drake does not quack, however the females do, but not loud. Any thoughts? I want to sell the ducklings but I need to know what to tell people the breed they are buying.

I would like a close up of the faces please, but they maybe either a mix or the one standing in the back could be a poorly marked Swedish? close up of face will tell a lot.
