If I was you I would not separate her, because she might get bullied even more when you put her back. I think it is a good idea to just put out more feeders or bowls in different locations. I have nine chickens and I have five different feeders and bowls of food in their run because the same thing happened to my black copper Marans. My Marans is blind in one eye also, so she definitely has a disadvantage and having a lot of different locations when it comes to the food has really helped her.Been hand feeding the last two I’m thinking of bringing her in the house in a crate for a few days too. I had a hunch I may need to look at a bucket feeder. Might just make a new feeder with more capacity and length too.
