Blind chicken?

[shailey]

So, I'm not entirely sure what's up with my hen. I was sitting with them like always, she seems fine, she's energetic as always and healthy, but her left eye is grey, instead of the usual firey-amber. It doesn't seem to bother her at all but I doubt its normal, let me know what this might be, I'd be greatly appreciated !

Could you post a picture of the eye? It could possibly be a sign of ocular Mareks disease when the colored iris fades to grey. The pupil can appear tiny or pinpoint and irregular-shaped. There are four forms of Mareks symptoms that can affect chickens—ocular, skin lesions, nerve involvement, and visceral tumors. Here is some reading about Mareks:
