Thank you for the articles. I've read the Great Big Marek's article before, a few times. It was helpful.I'm sorry to hear that
Had you noticed any change of shape or color in her eyes?
I know you'd mentioned you had Marek's in your flock. Unfortunately it can take it tole on some birds regardless of vaccination status. The vaccine doesn't prevent infection from the virus, it may help prevent or limit tumor formation and clinical signs.
Getting testing, if you haven't done so will give you some definitive answers. Some do vaccinate their own flocks. Do your research to determine if that's the best course of action to take. Others try to breed for resistance.

I'd never read the other one though. I just skimmed it and one thing that jumped out is that the herpes virus in the eyes / blindness is painful! That never occurred to me! All the more reason to act fast.
Another thing I saw is that Marek's can manifest itself in chicks in seizures. Omg. I had a hatched chick, part of the flock with 2 who both ended up going blind at 1 and 2 yrs old, who suddenly had violent seizures, at possibly 4 weeks old! It was absolutely horrible, and the chick did not survive.

I will return to this article. I see there's a lot of valuable information.
