Dark ones could also be Rouens.

For the dark ones, two eye stripes usually mean rouen and one eye stripe with the dot usually means mallard. Its hard to tell in the picture. I agree though that the others look like pekins

The dark ones could be mallards or rouens and the white duckings are pekins.

These were the rouen ducks I had about three years ago. One of them doesn't look like he/she has the second eye band. It really is hard to tell from a picture.
