Hunting, just a bad idea to go after this as if it were evil.

181. The term free roaming only applies to poultry raised for meat per the USDA

So you might be buying "free roaming" eggs thinking you are getting something special, but there is absolutely no guarantee by the USDA of this when it comes to eggs.

It really doesn't even mean that much when it comes to poultry raised for meat either. All it means is that poultry are afforded the opportunity to have access to the outside whether they actually do or not. A poultry farm can satisfy this requirement simply by having a small pen at one end of a long and narrow poultry barn filled with thousands of chickens. So if you're envisioning hens that are roaming green pastures hunting for bugs, you have probably been sold a bill of goods and paid more for essentially the same thing.

As far as hunting goes, if people didn't enjoy hunting, they wouldn't do it. If they don't do it, wildlife management fails. If wildlife management fails, animals die of starvation and disease. I don't think most people would consider this a good option. YMMV.
