Sakura Chicken -- a disappointment this time

Whenever I get a whole chicken from the supermarket, I would get "kampong" for soups or Sakura Chicken for roasts. Sakura chicken is really more tender (esp the breast), but this one time, I was very disappointed with what I got. It was quite tough, and worst of all, the feet had "burn marks". From what I saw on Jamie Oliver's Fowl Dinners, birds with such burn marks on their feet indicate that they have been bred in an overly crowded farm where the ammonia levels in their waste actually cause their feet to burn. :( I really hope that the welfare of the chickens isn't declining, coz' I'd imagine that it affects the consumers' health.
