what breed are they?

Can anyone tell me what breed these guys are? They are the size of rouens. Their heads are black, not green, so I'm not sure what they are.
They were very young when we got them. They were sold as female blue Rouen's. Clearly they are neither of those things.

Could they be silver appleyards? Very nice ducks! You really got a fantastic surprise, whatever they are!

They could be crossed? I was leaning toward the silver appleyard, but again..black heads?
They are really pretty ducks. Unfortunately, they are starting to get mean. My 2 blue Rouens have disappeared. I think they ran away from home because of these 2 guys. And now, they are starting to beat on my mallard.
I know it'll happen when there are 5 males and 1 female! That's why we got them...female. Ha! Jokes on us.
Luckily we just had a few hatch out and there is at least 1 female out of the 4 we kept.

Thanks for your response. I'm going to keep digging online and see if I can come up with anything more.
