Is the egg yolk larger in a jumbo than large or is it white that larger?

Here's why:

* Yolk size is related to the age of the hen: Older hens lay larger eggs with proportionally larger yolks.

* Egg size categories are based on weight: Jumbo eggs are the heaviest, followed by extra-large, large, medium, and small.

* Heavier eggs generally have larger yolks: Since jumbo eggs are heavier, they tend to have larger yolks than smaller eggs.

While the white of a jumbo egg is also larger than a large egg, the difference in yolk size is more pronounced.
