Bantam eggs as big as normal eggs?

[Duckchick2011]

Hi! I just ordered some bantam Polish eggs offline. They came in good shape BUT some of them are kinda big. They are about the size of a medium/small standard egg.

Is that normal? Is it possible I received a few standard eggs instead somehow???

usually the older the bird the bigger the eggs, but for the most part they should be smaller. It is possible that they are standard but it won't be shown until the chicks hatch.
