After reading excerpts from Gail Eisnitz's Slaughterhouse. (Google it!!!!!!!)

I haven't given up on chickens (and some seafood); which are the most abused animal of all; but I have cut down. I eat that at a couple of restaurants, and some times I'll buy canned chicken from Trader Joe's, and of course I buy chicken and other things I don't eat for the cats. I offer no excuses. I'm a hypocritical bastard with no will power when it comes to tikka masala chicken, tandoori chicken, East Asian and Mexican chicken. I just don't feel guilty enough. But I personally don't eat turkey or any other birds anymore. (The noisy brats behind us look like they'd make a great rotisserie, though.)
If you're going to eat this, be aware of the damage you're doing. Pigs are very intelligent animals, by the way. Actually chickens and sheep are smarter than people give them credit for, too. People just don't bother to notice or put any time into bringing it out of them.
