Ware Manufacturing Chicken Treat Roller - Interactive Pet Toy for Chickens & Birds - Durable Rolling Foraging Feeder - Perfect for Backyard Coops, Farms & Poultry Enrichment Activities

It took a few days for the chickens to figure it out. I had to help them a bit by shaking it and letting them see that stuff would fall out, but now they are hooked! They love pecking at it and moving it around with their feet. Great value for the money. It is pretty large and could probably stand to be a bit smaller, but who knows if that would make it to hard for them to use. Definitely worth the purchase.
