Ok, something i can help a little bit with. I get excited when i can help someone, cause i've been getting help non stop from everyone on here and i appreciate it. Anyway, my call ducks are a week old today, four of them. Two of them have no problems, but two of them don't clean themselves as well as the other two. I put a tupperware dish in the cage with them so they can swim and stop making a mess with thier drinking water. Well i noticed that two of them go under water and then preen themselves. The other two don't go under and preen, they had messy eyes for half a day. I figured out that if i put them in the kitchen sink with a good three or four inches of water,(just enough so thier feet can touch bottom if they get tiered) i keep sprinkling water over thier heads until they finally go under the water. I think they need to swim to keep thier eyes clean even at that age. I was realy worried about thier eyes until i did that, now they are nice and clear again. Yours may be worse by the sounds of it, but thats what i did. Someone else might come on and tell you something different. Hope she gets better, good luck...
