What breed are these?

[Lynserpole]

Hi everyone!
I'm new to ducks and just couldn't resist these guys when I went to tractor supply. I already have 2 pekin ducks that are 7 weeks. I was hoping for Khaki Campbells, but now I'm not sure what I have. Help please!

Bottom one looks like a black Swedish. I think the top is a cayuga. Hope that helps.
