Can someone help me identify my ducks, please?

I was told the grey one was a khaki Campbell and the black one is a black swedish. They black one may be but I'm starting to really doubt the khaki Campbell. :/

Sweeds have a white bib and Khaki are brown and a very muted 'mallard' coloring, if you will. The way the black/dark brown one stands, I'd say that is a runner. If they both stand up straight, they could both be runners.

I say you have a black and a blue runner.
