In Ukraine, chicken eggs will be sold in a new way, with two classes: Class A and Class B. Class A eggs must be clean, with an intact shell, with a sedentary yolk without clear contours, and free of foreign odors. They will also be divided by weight into XL (very large), L (large), M (medium), and S (small). Class B eggs are all those that do not meet the quality of Class A.
