there are egg farmers, working on a certain scale, who do have websites, explaining their methods and philosophies. worth checking out imho.
my go-to in the supermarket is nellie's eggs:
Nellies Nest: Nellie's Nest Cage-Free Certified Humane Eggs
this discusses the maze that is current egg labeling.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
