Duckling breed help!

[Marleigh33]

I am needing help on breeding my duck. We got them at tractor supply. We know what 2 out of 4 are but not so sure on this one or our other. We have several ideas but can’t seem to narrow it down. Please help! Both of the yellow/grey. We know for sure that they are not runners but other than that we are lost. Thank you for your help

The second to last picture looks like a blue Swedish to me. The dark duckling in the last photo looks like a black Swedish. The first couple of pictures are hard because of the red light but I believe I see a Khaki Campbell and maybe a Welsh Harlequin.
