Bird randomly and instantly went blind

[Ruler of the Roost]

One of our newest pullets started freaking out when we walked in. Wouldn’t fly, acting irrationally. Immediately ran in my wife’s general direction when she started talking. When my wife picked her up she calmed down and just layer on her chest. Then she wouldn’t get off. I started to examine her and noticed that her eyeballs looked like they were shifted straight back. Not sunk in, but literally sitting too far back in the eye sockets. I started making irrational movements with my hands around her head… absolutely zero reaction. Even put my fingers right next to her eyeballs. Didn’t blink and didn’t move. What could be causing this?

When is the last time you know for a fact this chicken could see perfectly well?

I can’t for fact say ‘perfectly well’ for the simple fact that I cannot verify whether she did or did not have issues that may or may not have been progressive. Bit I can say that before yesterday she was acting like a perfectly normal chicken.

It just looks to me like more of the membrane is showing than should be

Hmm. Would flash pictures show what the pupil looks like? Or is the nictitating membrane covering the eyeball? We really need closeups if possible in bright light so we can see the shape and color of the pupil if possible.
