Our hens are fed with Mich. grown corn and are United Egg Producer certified. This stringent certification means our farms undergo annual third-party audits to ensure that the eggs are produced in strict accordance with United Egg Producers Animal Husbandry Guidelines. Our hens never come in contact with a rooster, guaranteeing that all of our eggs are unfertilized. An end user will never open an egg that contains an embryo. And Hamilton Eggs are fresh – typically processed the same day they are laid.
