I can't find this from a reputable source, but a FB friend shared a Buzzfeed story about the advancement in egg selection. Apparently Unilever has developed a technique to sex the eggs before they hatch and therefore can prevent the males from being born. As you may know, males are killed on day 1 since they serve no financial benefit to chicken farmers. Therefore, they can stop the practice of sending the male chickens to the macerator.
