How to tell if a duck laied an egg?

[Cool_Catrules456]

I just got my first duck egg, I have two females. I would like to know who laied it, and pull them to the side and give them more calcium. I have chickens but I am pretty sure this is a duck egg. I only have one white layer, and she has been laying constantly. So that only leaves the ducks. It is a white egg.

The ducks are pekin drake X khaki Campbell hen. Any ideas?

They hatched on may 20th.
