What’s wrong with her eye?

[Shanshan315]

Hi! One of my hens has one dilated pupil and one not. I can’t tell if she can see out of her eye or not. There’s no gunk, no sign of injury. The only recent difference is that she’s been sleeping on the floor of the coop instead of the roosting bar.

Not an expert, but my first thought is stroke or other brain injury. Has she had trouble balancing?
