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.
