The issue is that chicken in the US (even the "free-range" ones) are often factory-farmed, else I would have gladly recommended it. I was extremely astounded by the (high) quality of free-range chicken and eggs one can get in the UK. In the US, it's more likely for your grassfed beef to be free-range than it is for your chicken. Coming from a heavily pescetarian culture, I wouldn't recommend a lot of seafood today. Fish are loaded with oceanic carcinogens, not to mention you have even little control over how they're sourced (it's nearly always a factory ship).
