There is a lot of different ways to entertain the birds. I have a grass catcher and when I mow with it I collect the grass and put it in their pens. They love to scratch through the grass clippings. You can also use leaves. I also now and then put flock blocks in their pens which they love to peck at. I made a chicken ladder out of some scrap wood for the birds to climb on. I have also hung cabbage and lettuce which they also love to peck at. When I pull the plants like broccoli, cauliflower, etc, out of the gardens after harvest I put the plants in the pens and they will devour the leaves which leaves only the plant stems. During the winter months after the grass stops growing I buy bales of alfalfa which they also love. Good luck and have fun...
