Kirkland Signature Organic Extra Large Eggs are sourced from free-range hens raised with access to outdoor environments. These brown eggs are certified USDA organic, meaning the hens are fed an all-organic diet free from GMO feed, animal by-products, and chemical additives. The hens receive no hormones or antibiotics in their regular diet, only as treatment for infections when necessary. Each pack contains 2 dozen (24 count) extra large Grade A eggs.

Free-range hens have outdoor access and are raised in cage-free barn environments, though they are not pasture-raised. The organic certification ensures the chickens are fed certified organic feed consisting primarily of corn and soy. These eggs are kosher certified and must be kept refrigerated. Costco is committed to sourcing 100% cage-free or better eggs across all locations, with 97% of eggs sold worldwide meeting this standard as of 2022.
