My buddy, Kurt at culturaloffering.com thinks that this is something we need to know.
I suppose so and I may design an experiment to see how different diameters of the bottle muzzle effect the results.
In the meantime, here is a photo I took of a rare, double-yolk a few weeks back. My family was amused that I stopped to take a picture of this. I said to them, I never know when I can someday use it and it is always better to have something and not need it than to need it and not have it…
I am told that a double yolk occurs approximately once in every one thousand eggs.
