Roaming chickens generally also have access to outdoor
areas, but the labeling laws have no requirements as far as
the size or quality of the area goes, nor for how long the
chickens must be allowed out. Fact of the matter is, most
of these chickens never set foot outside the barn. These
labels are not audited—you’re going on the word of the
producer alone.


  • Certified Organic eggs come from chickens kept in open
    barns or warehouses with an unspecified degree of
    outdoor access (again, for all intents and purposes,
    probably none). They must be fed an organic, all-
    vegetarian diet free of animal by-products, antibiotics, and
    pesticides, and farms are checked for compliance by the
    USDA.

  • Certified Humane eggs have been verified by third-party
    auditors, and this label requires stricter controls on
    stocking densities, giving the chickens more space and the
    ability to engage in natural behaviors like nesting and
    perching. Producers are not allowed to engage in forced
    molting, the practice of inducing hens into a laying cycle
    by starving them (this practice is allowed for all other
    types of eggs).

  • Omega-3–Enriched eggs come from chickens that have
    been fed supplements made from flaxseed or fish oil to
    increase the levels of omega-3 fatty acid—an essential
    fatty acid touted with several health benefits—in their
    yolks. While some people claim eggs high in omega-3s
    have a “fishy” aroma, in blind tastings, I’ve found no
    significant differences in the way these eggs taste.
