A couple questions on grading eggs. 1) In Illinois (and New York -plan on moving there someday) require you to have some kind of certifiaction to grade eggs? 2) how do you grade an egg (or is there instructions/guidlines somewhere)? I ask because I was reading up on the laws for being able to sell eggs and in Illinois. If you sell eggs right off the farm where the chickens are located they do not have to be graded but if you take them off the farm to sell they must be graded.
