I used to live near an egg farm. A commercial supplier, but they had a little stand by the road where they did direct sales. They sold all the grades of eggs you don’t see in stores, by the flat. One of the options was double yolkers. Occasionally you’d find a triple.

You can tell before cracking the egg?

You can shine a light through the eggshell to see what’s inside. It’s called candling.

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

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?

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
