Who laid these

[mbcaring]

Are these all chicken eggs? I have pullets, hens, Muscovys, and guineas. Originally I thought the big one was my first duck egg and the little one my first guinea egg. But not I think the little one is a pullet egg and the big one might be a very large chicken egg. Help please.

I am just guessing.....I have never seen eggs from guineas. My GUESS is the one on the right is a duck egg. The rest look like chicken eggs to me.. With the one on the left being a pullet egg.
