You can try blinders. I recently had to put blinders on a New Hampshire cockerel who turned into a complete butthead, & started attacking us. He still tries to attack, but he can't coordinate them very well since he can't see directly in front of him. Most he can do now is bite, & pull on pants.
Here's my other rooster with blinders to show you what it would look like.
