eyes gone different colours

[chickenfan]

One eye has gone much paler than the other on one of my hens (or perhaps one eye has gone a lot darker). Not sure what this means or perhaps if one eye could be haemorraging. She seems to be laying and looking well otherwise.

Could be a cataract, but that's unlikely? Heard that an eye infection can cause that effect? Could also be the inner eyelid down? Never noticed any colour differential in any of ours ever like that Chickenfan. Have you checked her eyesight from both sides?

Thanks Chris. Good idea to check her eyesight. Stupidly I forgot to ask the Poultry Vet about it today.

Apparently it could be glaucoma. If it was Mareks, the pupils go irregular. Bird seems very well.
