Free Run eggs are produced by hens that run free in an open concept barn that has a variety of nests and perches. They are not housed in cages. They are able to socialize and move about the barn without restriction so they can express natural behaviours. They get plenty of exercise and enjoy excellent health and vitality because the environment is well maintained and kept free of contamination or harmful bacteria. And because eggs are porous, this clean environment contributes to production of healthy eggs as well.
