The New York Times has a pretty good article about the information you’ll find on an egg carton … what’s required, what the government allows them to claim, and what’s just creative story-telling.
“For eggs from chickens that live in the sort of utopia conveyed by the images on most egg cartons, look for “animal welfare approved.” Available in limited markets, it is a new label by the Animal Welfare Institute that is given only to independent family farmers. Flocks can have no more than 500 birds, and chickens over 4 weeks old must be able to spend all their time outside on pesticide-free pasture with a variety of vegetation. They must have access to dust baths and cannot have their beaks trimmed (a practice on crowded egg farms) or be fed animal byproducts.”
