what do egg grades mean?
In the grading process, eggs are examined for quality before they are sorted according to their weight (or size). Grade quality and weight (size) are not related to one another, and eggs of any quality grade can differ in weight and size. In descending order of quality, grades are designated AA, A and B. Grade AA â These eggs are nearly perfect. The whites are thick and firm, and the yolks are free from any defects.
