As
@aart says, the USDA has a chart for such things - and its based on the weight of a dozen eggs, not each egg singly (though I suspect commercial egg production scales eggs individually during inspection, since we consumers put value on uniformity). You should look into your local and state laws before making representations about egg sizes, EVEN IF TRUE. Here in FL, for instance, a Lmt Egg and Poultry License allows me to sell shell eggs and processed birds for human consumption, but I can't sell them in cartons, and I have to prominently display a sign, substantially "These eggs have not been USDA graded for size or quality". This is one of those situations where State and Federal lawmakers have decided truth is no defense, and the cost of fighting reasonably exceeds profits of sale by many, many orders of magnitude.
I don't recall ever looking at MN's laws specifically, can't offer keywords to search statutes on, besides the usual chicken poultry shell egg. Sorry.
