Can you tell what kind of duckling this is?

So I ended up offering to hatch some duck eggs for my chiropractor (don't ask lol) but they're new to everything and got the eggs from someone else. They're clueless what breed they may be. All I know is that the eggs are white, took 4 weeks to hatch and the first one out looks rather dark. I know that's not much to go on. There is 1 egg left in the group that must be muscovy because it looks like it has another week to go but I'm not a duck person so I'm clueless on these ones. I know this isn't much to go on and I'll put up more pictures later once they're done hatching, dry and fluffy.

Updated picture. The yellow one looks crested maybe.

It looks like quite a mixture to me. Possibly Black Sweddish with the yellow on chest, the black one might be Cayuga, the brown one Khaki Campbell, and not sure about the other two. Cute ducklings though.

Thank you. Once they were all fluffy I was starting to think they were just a mix.
