Chances of finding a double yoke in an egg is about one in a thousand. Old folklore says that it is a sign of good luck coming. One can only imagine how surprised I was to find one and another when I cracked the second egg.
“According to the American Egg Board, “Double-yolked eggs are often produced by young hens whose egg production cycles are not yet completely synchronized. They’re often produced too, by hens that are old enough to produce extra large-sized eggs. Genetics are also a factor. Occasionally a hen will produce double-yolked eggs throughout her egg-laying career.” Ask USDA
I recently enjoyed 1/2 dozen organic double-yoked eggs
