I brought this gal home a few days ago. She seemed fine other than missing a few feathers around the left eye. Yesterday, I noticed her eye bubbling (not foaming). I flushed it with saline. I isolated her. When I checked her this morning she had a white purulent discharge. Her third eyelid is quite prominent. She has been acting normal otherwise, still eating and drinking. Any ideas? Not sure if she had an injury prior to coming to us or of this is something more serious. Thanks in advance.
