White eye in hen

[SDiaz]

Hello,
My Hen’s eye has been shut for a while. I haven’t noticed it until today, however, my son says she open it up and it is white.
I don’t see any swelling. Just white.
I have been spraying Vetericyn plus on it a few times a day. She still eats and drinks and walks with the other five hens.

Here is her eye closed abs then barely open. You see the white part. She quickly ran off when I try to get near.
