They're all basically the same. Different labeling groups have different requirements, it doesn't really matter. The fact of the matter is that the business is going to do whatever it takes to make as much money as possible, and that means less space and freedom for the animals. You can come up with as many requirements as you want, but the egg producers, like any business, will do as little as they possibly can do to meet them. It's just not possible to treat these animals with empathy when your job is to take from them as much as you can while giving them as little as you can.

As bare as these requirements are, they only exist because without them there is literally no reason to try. And even with them, there is only the incentive to legally meet the requirements, nothing else. The labels are for us, not the chickens.
