Duckling breeds?

[macyduck]

I bought 6 new babies
I know two are Rouen
I think 2 are Swedish
And the other two I'm not positive
Thinking cayuga/or khaki
And the last one I'm thinking crested buff? But looks just like a welsh harlequin but with crest?
Idea please!!

 

[chickens really]

It looks like a crested Buff....And the one is possibly a Runner?.....
Very cute little Ducklings....
