i would isolate her and put her on clean paper towels. You can use Terramycin Ophthalmic Ointment in the eye. i buy mine online and use it for my cats, chickens, ducks, and even myself. It's a very soothing antibiotic. Sometimes bubbly eye can indicate a respiratory infection. i have also had birds eyes bubble or look gunky because they got something in it or have a minor eye infection. Are you seeing any other indication of a respiratory issue like nasal discharge, sneezing, or trouble breathing, rales? Are these new birds in with existing birds? Because you always want to isolate any new birds from your others for a period of 4-8 weeks, in case they are carrying something contagious.
Please let me know how things are going.
