Egg color and who might have laid the egg question

[WriterofWords]

How can you tell the difference between a green chicken egg and a green duck egg? I thought I had some hen laying beautiful green eggs, because they were in a nest with some brown and white chicken eggs. I also have Runner ducks who lay green eggs, but these aren't as big Hershey's eggs. I caught a duck sneaking out of the nest so now I'm not sure if they are chicken or duck eggs!
Is there a way to tell visually?

duck eggs feel a little 'waxy', chicken eggs don't

Why do I see a bunch of green eggs in the bator just to see what comes out?
