There is a free rehoming forum here also, and a Where Am I Where Are You forum that is organized by location. Have you posted her on those? She is so beautiful!
Oh, the poor thing! You know, I wonder if she may be better off as a house duck? She'd definitely be more prone to predation if she were outside since she can't see. But if she's already bonded to other ducks then there's no other choice. Oh, I hope you find a home for her, I'm all the way clear on the opposite coast! My cousin lives in North Carolina though, I'll ask if she knows anyone with a lovely farm.
