There is already lots of good information on this thread for nipping the pecking issue, but here are just a couple of things I do for my girls to keep them occupied. If your chickens already have sufficient space (first requirement for keeping them peaceful), you could toss these into the run:
* cabbage (whole, half, or wedges. Mine like red cabbage best.)
* cauliflower (whole, half, wedges, whatever.)
* winter squash (try halves)
* pumpkin (for a real challenge, leave a whole one in there and let them go to town on that.)
* fallen leaves (already mentioned, I think)
* straw (less likely to get eaten and cause problems than hay, but still provides lots of busywork as they scratch it up and look for seeds)
* corn cobs (after family dinners!)
* apples (try whole if they need a big job)
The bottom line is, chickens are like other animals: if they are confined, they need a job. Bored animals (and people) can become unhappy, depressed, and violent. In the wild, they would spend their days ranging in search of food. Give your chickens some "wild" stuff to range through, or maybe even perches or other objects to explore, and I'll bet you end up with happier chickens.
Good luck!
