Lady Di a six year old Brahma, has had a tumor over her right eye for over a year now without any noticeable discomfort. Today, I saw she was scratching her eye, and upon close inspection, I saw it is swollen between her eye and her beak. I flushed her eye with saline eye drops, and it helped get rid of the bubbles. I massaged the swollen area to see if there was any pus, but none came out. Any advice on what I should do for her?
