IMHO really rare, but then happened with several eggs from the same batch.

        No but the thing is, they ONLY sell double yolkers. That way they don’t have to check. It’s double in every egg. Hmm?

        Double-yolkers are bigger and usually weirdly shaped in my experience. It’s not a guarantee or anything, but they never seem to look like a normal egg

        I think some chickens are more likely to lay them than others (due to age, or genetics). After that the eggs are somewhat larger, and you can check by shining a light through it
