I agree w/grass fed but not free range. It's kinda a joke what they consider "free range" and get away with it. Watch “Super Size Me 2: Holy Chicken.”...this is just a clip.
"The U.S. Department of Agriculture (USDA) has defined the term "free range" only for chickens, not for eggs or for other livestock, such as cattle. For chickens to be free range, the birds must be "allowed access to the outside," according to the USDA."
