I had a hen get a pox right on her eye, the pox eventually sealed her eye shut, and got dried out and bigger like a wart. She didn't want me to touch it, and I just let it be. I did not treat it, and it got about as big as a lentil, sticking out flat wise from her head like a flying saucer, and she didn't appear to be in any pain as long as I left it alone. In about a week it dried up and fell off and her eye was perfectly fine under it, just lost a little bit of pigment under the actual scab area, which filled back in in a few days. I would just leave it alone if I were you. Try any home remedies in your own eye before you put them in your chicken's eye just so you know what you are doing to her. If it ain't good enough to put in your own eye, it ain't good enough to do to your chicken.
