My bleeding blind duck

Hi, I was hoping for some help, I have a blind duck who has recently lost some feathers from her wings making her bleed. She started forming scabs and healing then my chickens started chasing her and making her bleed again! I have separated her, it took her about an hour to settle. I'm worried she will stress herself out because she's alone??? I don't have the room to separate the peckers and leave her in with the other ducks. Will she be ok for a few days by herself? She can hear the others just can't see them... Obviously! Thanks!
