The hens that produce our Nutri-Fresh Fertile eggs are fed the same diet as our Veg-a-Fed and Humane Harvest producing hens. These hens however, have some roosters living along side of them and with their help produce naturally fertilized eggs. We never use artificial insemination for our fertile eggs, only the way nature intended. These fertile eggs are produced in both white and brown and are packaged in the same recycled cartons as the rest of our products.
