Olive green duck egg?

[Peep Nerd]

First time with ducks. I have 4 cayuga mixed girls. Have been getting nice size, cream colored eggs for about a week or so, one or two a day. Today I have 1 small, olive green egg. The only other birds in the coop overnight were seramas who have not laid any eggs yet. This egg is about 2inches long. I think it's too big to be a serama.
I'm so confused! Could it be from one of the ducks?
Thanks!

Cayaugas do lay green eggs, so yes, it's almost certainly from one of them.

And by almost certainly, I mean, "No serama laid that egg."

Thanks! That was my thought, too. I just didn't expect a small olive green duck egg. lol
It's gorgeous, though!
