My father has a turkey and for about 4 to 5 months now her eye has been swollen shut to the point you could not even see where a eye is supposed to be. This week the swelling has gone down enough that you can see where she should have a eye if she could open it. Also yesterday I noticed something white that almost looked like a maggot in it. Today I went to check on her and it is oozing and smells rotten. She still eats and laying eggs. I have gotten attached to her so I do not want to lose her. I have been letting nature do it's thing but what could be going on?
