"multiple yolks" news and stories

Double-yolked eggs are reasonably common for ducks and chickens, despite the fact that we so rarely see them in stores. It is estimated that 1 in 1,000 eggs (out of 50 billion produced annually in the US) have double yolks. Eggs increase in size as the number of yolks increases, but most of them are caught by "candling," or holding the egg up to a light source to reveal a shadow of what is inside the shell, and used for other egg products instead of being mixed in with single-yolks. Stores that do offer the eggs usually have one local source for them. The chickens, ducks and other birds that lay them have a genetic tendency to produce the eggs, so if a farm is stocked with such birds, most of their eggs with have double yolks. The eggs are popular with anyone who likes yolks and are also believed to be good luck by many.

Far less common are multiple yolk eggs, including triples and quadruples, like the one pictured above. Apparently, the greatest number of yolks found in one egg was nine!

If you can't find any multiple-yolk eggs in your neck of the woods, you can always separate one egg, add the yolk to another, and save the white for later.
