I thought eggs were graded by size. I guess this makes more sense for the age part. I guess you can have small AA grade eggs?Grading Eggs
Before being sold in Colorado, all eggs shall be graded into Colorado consumer grades and weight classes which are based on USDA standards of quality. The grade of an egg is a guarantee of quality, AA being the highest. The grade is most easily determined by candling to gauge the size of the air cell in the large end of the egg.
