I'm so sorry you have to deal with this, and for those poor little ducks who don't deserve this. Thank you for helping them.
I think with appropriate housing and nutrition they will improve greatly. Ventilation and a deep clean water bucket to wash out the eye might help a lot. When my duck had a less serious eye issue I took her to the vet and was prescribed eye drops, but that was really expensive. I believe for at home treatments people rinse with saline, and sometimes use Terramycin ointment (which you can buy without a prescription). I don't know if an antibiotic ointment is indicated - or if the eye just had debris accumulated.
I would definitely keep the girl separated from the drakes and do what you can to advise the owners when they return. They must not know that girls can be injured and killed. A 3 to 1 ratio... That poor little girl.
You are doing a great job.
