I have heard wonderful things about New-Zealand. Being South-African born, I'm not too fond if your rugby team though :)
Jokes aside, you are correct. Pasture-raised grass-fed livestock is far healthier for us.
Logically, it doesn't make sense to keep a chicken locked in a batteat cage, unable to move, eating grains and other feed (it wouldn't usually eat), under a UV light which tricks their brains to thinking it is always day. This artificial environment is designed to speed up production, that's the sole purpose.
So yes, Free range is definitely healthier, for many reasons.
Thanks for your comment. Hopefully I will visit new-zealand some day
