The eggs come from what's known as 'pastured hens'. The chickens live in mobile buildings or tents. At the start of the day, the farmer opens the door to the building to let the chickens out. They roam around in the grass, eating clover, bugs, worms, and maybe even some stones to aid their digestion. At the end of the day, the chickens naturally return to their roost, and the farmer closes the door to keep them safe and secure overnight. Every 3 days, the buildings are moved to fresh pasture.
The only way to get a more nutritious egg is to have a chicken in your backyard.
The eggs from these farms have been tested by CBC Marketplace and shown to be more nutritious than any conventional or free range eggs they tested.
