Identify these duck eggs?

[KDailey]

I need help figuring out which ducks are laying these eggs.

I have a pair of call ducks, 1 blue swedish hen, 1 chocolate runner duck hen, and 2 what I think are harlequin ducks at least one female and hopefully a male.

The two mint green eggs are slightly larger than my old english bantam eggs and the white one is larger than a normal chicken egg.

The smaller eggs are most likely your call ducks. They will lay smaller eggs than the larger ducks.
My guess, is the large white egg could be your swedish, harlequin, or possibly your runner. A lot of people say their runners lay greenish tinted eggs, but I have a few fawn and white runners that lay white eggs. So it is possible that your runner hen is laying the larger of the 2 greenish eggs.
The best way to tell is to separate them for a few days. When I want to know who is laying, I separate them by breed (make sure you have at least 2 ducks together, otherwise they will get lonely!) I do this for 2-3 days just to see who is laying and who isn't.

The egg in the middle looks like the same egg that my harlequin lays.

eggs to the right and left are the call eggs

I'd say the middle is a Swedish egg and the right one is a runner egg, not sure about the left one though.
