Eye infection?

Question
Yesterday morning, I woke up to find out that my cockatiel (lutino female) 's left eye was half closed and gummed up. I wasn't that worried, thinking she just had a bad night's sleep. However, the next day, the condition looks far worse off. She can't open her eyes most of the time, and when she does, it's red and watery; the feathers around her eye all fell off, and it looks rather frightening. I applied some eye ointment for humans, but I really don't know what's causing this. Should I be worried? How long will it take to heal?

Hi, Fira.  Thanks for posting!

You need to get your tiel to an avian veterinarian right away for a medical evaluation (not a cat/dog vet, but an exotic animal vet).  This problem could be caused by a number of things and your tiel likely needs antibiotics that only a vet can provide.  The vet can diagnose the problem and give you the correct antibiotic for what ails your bird.
