So sorry about your bird. I hope he makes it but I don't think he can function without his eye sight and maybe culling him and the bullys might be the thing to do. Everyone is different.
Long story short. I had two hens that were really aggressive so I put them in chicken jail for a week where they could see the other birds and the other birds could see them. When I let them out one was ok but one was still a bully. I put the bully hen back in the chicken jail which is a rabbit hutch that I had used as a brooder, for another week. When I let her out she was still a royal bully. I understand they have to establish their pecking order, but one hen was after blood so then I would squirt her with a hose when I saw her pouncing on one of the younger birds. Every time I saw her jump on and wail away on one of the pullets I squirted her with a hose. She eventually got the message or was getting tired of being squirted and decided it just wasn't worth it.

Hens go broody when you don’t want them to… and won’t go broody when you do.
