I don't know where you live, but you have to be aware of exactly what the labelling rules are where you buy eggs. In Britain, free range only means that the hens have access to open-air spaces, but not that the hens ordinarily inhabit that area. Considering the strict hierarchy that chickens form (the original pecking order), some individuals might never get an opportunity to be in this open-air space.
Organic is a different protected term in the UK that has additional conditions, such as a more humane limit on the density of the hens' accomodation and stricter dietary requirements.
It's a really complicated issue with some fierce lobbying from the intensive farming industry to loosen the welfare requirements, but suffice it to say that there is a 'euphemism treadmill' of constantly changing terminology depending on whether the factory farming or the welfare lobbies have the upper hand at any given moment.
