Help identify duckling

[Vegeta]

I'm guessing the little black one is a runner. And the one inter left is a Rouen mallard. Correct me if I'm wrong. The one in middle I already know it's a wild mallard because that's the one I hatched.

The solid black one could be a cayuga. My cayuga ducklings were solid black- feathers, bill and feet/webs.

Mallards have one eye stripe rouens have 2! Looks like a mallard to me.

This is a good picture of rouen stripes.
