Who the hell cares about stupid chickens and pigs? Have any of you ever actually MET a chicken? They're positively moronic, with or without their heads attached. Pigs? Tasty, but ultimately only surviving because we take care of them. Javelinas? Yeah, keep them "wild and free" but domesticated porkers are just that - meat waiting to be cooked up and consumed.
What I want Burger King to do is better care for the HUMANS in their employ. Better wages, benefits to include health, education, retirement, etc. Oh, and making their food less revolting would be another good thing. Plus cleaner bathrooms. I can't recall ever being in a clean BK lavatory.
Anyway, humans first! We're not at the top of the food chain because we're "friendly."
