Can you tell me why some eggs in the carton, are stamped , and some are not ? Is it safe to eat the eggs that are not stamped ?

My recipe calls for room temperature eggs, is this safe? How long can an egg be out of refrigerator and still be safe?

If you get your eggs graded how do you get them back to sell?

Canada A on the cartons doesn't guarantee Canadian eggs. Some cartons are not marked Product of Canada. How do I know they're from Ontario?

Why am I seeing eggs stamped with a code?

What does the stamp on an egg mean?
