An egg distributing company In my town is marketing "GOLD" eggs. Supposedly there is 325 mg of omega 3, 160 iu of vit D, and 600 mg of lutein in each egg. They are not organic that I can identify. So is there an additive I need to give my free range chickens that I feed non GMO food to make them comparable? They are charging $3.00 a dozen for these eggs.
