if you can find a tetra 250 that would be a good start, then what i would do is use a bleach solution in squirt bottle and soak her eye 2 times a day or so, Pick her up and use a Q-tip and pry open her eye and look inside if its pussy twirl the Q-tip around against her eye ball and pull out...
I know I was pretty lucky but at the same time in comparison to how other people I know take care of there birds I did alot more work to keep them alive, I lost a few birds but not as many as I could have
