Chickens are a staple of every normal human worm babys' diets. So, for people like my buddy Rex, who says you are what you eat, and since he eats Chicken for breakfast, lunch, and dinner, he is a chicken, here is a page where you can become a chicken! w00p!

And then for those of you who don't necessarily want to be a chicken, rather you just want to control them -- maybe you live on a farm -- maybe you have one as a pet -- maybe you want one to think it's an Ostrich -- why not learn to hypnotize them?
