I use a couple driveway markers. They're light weight and give me several extra feet on each arm. And giving them a swat doesn't injure them. I previously used a yard rake, but it was hard to maneuver quickly. When I walk away I swing one back and firth behind me to discourage my leghorn from coming at me. He jumped at my leg once when I was feeding them and seemed surprised when I didn't budge. Now when he acts like he's going to charge I move on him first.Than get yourself a tool and work on keeping him away from you, you also need to dominate him, so do as your hens are doing. You can get rid of him later if he becomes worse.
