I've never seen it personally, but I've heard that chickens can be housebroken and trained to use a litterbox like a cat. As animals go, some of them are quite intelligent, and some of ours even respond individually to their own names in the same way that a trained cat or dog might. They realize when one of their own is missing, and if they see another chicken eaten or killed, they remember what did the deed and how, so if you eat your chickens, make sure to take out their buddies where they can't see you. Yeah, they'll miss the one that's gone for a little while (especially if it's a particular rooster's favorite hen) but they won't be psychologically scarred and distrustful of you if they don't catch you in the act.

In all honesty, there's really nothing wrong with eating the pet chickens that you've named and loved. In America, we tend to think that eating something that you've handled, talked to, and treated like a pet is a barbaric practice, but in truth it is the most humane thing you can possibly do. After all, when you eat a chicken, whether it be your own or one diced into a burger or a taco you pick up at a fast food joint, you're asking an animal to give up its life in order to nourish you. There's nothing wrong with that-- chickens and other livestock have been feeding humans (and other animals) in some form or another for thousands, if not millions of years, and if you're going to be grateful for that substantial contribution to humanity as a whole, why not embrace the animals that you're going to eat, give them a good life, and let them live happy and free until the time comes (as it does for all of us) to fulfill their most profound duty in the greater scheme of things.

After all, if you were a chicken, would you rather be raised commercially, in the vicious and cruel system that produces most of the meat we eat in America today, or would you rather be treated like a pet, cared for and loved, handled and fed as much as you can eat with the freedom to go wherever you want? You're going to get eaten either way. It just makes more sense to love your chickens!
