Ware Chicken Peck-N-Play Boredom Busting Ball
You can stuff this rolling toy with chopped cabbage or other treats your chickens enjoy, and they'll really have to work to get the goods! Chickens in confinement without adequate stimulation may pick on each other out of boredom. This ball will liven things up for them.
Other products which can help greatly with boredom are listed below, in the "related products" section. If you're concerned your flock is suffering from boredom, you might also try adding fall leaves, or grass clippings for them to dig through and spread. (These additions also help the poo in their run break down and compost, too!)
