Sissi has had solid white eye discharge in one eye since she was a year old. She is 9 now. My vet has tried all known antibiotic treatments to no avail, and has no idea what the problem is. So, I have been cleaning her eye twice a day for the last 8 years. Recently it has got worse, and I know she has lost her eye. I remove the solid stuff and apply a gel. It doesn't worry her in the slightest (although she hates me now for gouging out her eye to clean it and runs when she sees me!). But does anyone have an idea what could be wrong? I thoughy maybe eye worm.. but she doesn't scratch her eye at all, and my other hen, Henny 11 years old, has never been affected. Appreciate any ideas.
