What Breed Ducklings do I have?

[JanSokoP]

Special ordered from Blains, 2 pekin and 2 rouen females, to introduce later to my male pekin and male rouen. The females differ greatly from the pekin we got last year. They are downy with yellow bodies and black down on their heads. Their beaks are black and feet are gray. The female rouens are interesting as well....one looks like a rouen and the other is all chocolate brown down with black feet and beak. My order is not as I had hoped but at this point I am just praying they are all females. Does anyone have any ideas of what the mystery "pekins" and the chocolate ducklings would be for a breed?

It might help if you post some pictures of the ducks.
