the 2 white ones are pekins the one In the first pic looks like a cross but I could be wrong

The drake looks like Rouen or Rouen mix to me, the first white duck appears to be at least part buff, and the second white duck looks to be at least part runner.

The first white one looks like a pekin and the second looks like a runner.

Our male Roens looked like the top one. The feather color gradually changes to the adult plumage. He is molting now and looks that way again.
