White Eyes?

[ChickenLover520]

Hey!
For some reason, one of my chicken’s eyes is turning white. It doesn’t look a a cataract and there is no worm or film coming out. It is literally just the iris turning from an auburn color to white. I am baffled because she seems to be acting normal. Should I be worried?

How old? Chickens can get cataracts, and eye injuries. Things like Mareks can cause pupil changes too. Can you post a picture?

I have looked up Marek's disease and it could quite be the case. She should be turning 3 sometime soon...
I'm so sorry! I don't know how to upload pictures. Do you know when symptoms would start to occur?
