Have you ever cracked into an egg with a double yolk? Lucky you! Ever cracked into several eggs in your dozen to find double yolks in more than one egg? It might seem like finding a four leaf clover, but there is actually a reason this happens fairly often.
By themselves, double yolks are fairly rare – you might find them in 1 of every 1,000 eggs. These eggs typically come from our younger hens who are still learning how to lay eggs.
As you might expect, double yolked egg shells tend to be pretty big. In fact, they are usually graded ‘Super Jumbo.’ Eggs identified as Super Jumbo are too large for our packing machine to pack into cartons, so they are moved to the hand packing station. At Nellie’s, these eggs are still labeled as Jumbos, even though they are technically Super Jumbos. As the hand packers fill their Jumbo egg cartons with Super Jumbos, more than 50% of those will include an extra yolk. So that makes something fairly rare in nature suddenly appear rather common, simply because they have all been grouped together during the packing process and put into the same cartons.
So if you crack open a Nellie’s egg and find a double yolk, you’ll actually be pretty likely to find another ‘eggstra’ yolk or two in your dozen. And because those cartons are hand-packed and placed in cases together, you could find a whole grocery display of Jumbo dozens that have a high likelihood of containing a double yolked egg or two!
