Possible Mareks disease? Grey pupil

[bribre]

I recently purchased 8 young chantecler chickens that are 8 weeks and 12 weeks old. One of the 4 cockerels is definitely half blind. It's one pupil is slightly grey and looks as if it's kind of hollow? Really don't know how to explain it.. but what I'm wondering is how young would signs of Mareks start to show?

I'm thinking my best bet would be getting him tested (if I can find a place to test him) but just wondering if anyone else has had similar problems.

Not the best pic but you can kind of see it..

It's hard to say what's going on. It would be best to have some testing.

Marek's symptoms generally on average start showing up around 12-25weeks, but it can be seen at any age.

Thank you for the links.

I'm guessing there's no point in separating him as if it is Mareks the others already have it..

Not sure where to start finding someone that would test him.. I was thinking of calling a college close by.

I'm not sure who you would call in Canada. I would think your local vet could point you in the right direction.
