Help me identify the breed of my ducklings!!!!!

You might have to wait to be sure as all those look about the same at that age. Where are they from?

 

Not rouens- rouens have a double eye stripe!

They are mallards. Muscovy, while they can have an eye stripe and yellow dots on the back, look different in body type and they have a large "bean" on their bills. The babies in the pic do not look to have that

 

Are we sure they're not grey calls? Where did you get them?
