I think a good free-range chicken is a better way to go if you're having to buy mass produced birds from the grocery store. Usually more available & cheaper than organic or free-range turkey. Watch the chicken packs - some of them are brined too:

LIVINGSTON, Calif. – Amidst an increasing national focus on sodium as a critical health issue, West Coast poultry producer Foster Farms today launches a comprehensive consumer campaign to raise awareness of saltwater-injected or “plumped” chicken. ”Plumping”— or the injecting — of fresh, raw chicken with saltwater is a practice employed by many chicken companies which costs consumers money and contributes to serious health issues. Under current USDA labeling laws, brands that plump their poultry may still label their chicken as “100% Natural” or “All-Natural.” According to a new survey released today, consumers are largely unaware of plumping and would prefer that only non-injected chicken be labeled as “All-Natural.”
