I'm sorry about your hen. I agree with @Eggcessive in the video it does look like neurological symptoms. That coupled with the sudden blindness, I would lean toward Marek's as well.I don’t have any poultry drench on me, I can go to the feed store after my daughter wakes from her nap. Would this help if it’s a vitamin D or E deficiency?
I sure hope it’s not Mareks...
The Poultry Nutri-Drench won't hurt her.
