Poor eyesight-- Mareks?

[blossom01]

I have two very sweet 6 week old Buff Orpingtons. I bought them about 3 weeks ago from a feed store, so I'm not sure if they were vaccinated for Mareks or not. One of the girls has had terrible eyesight from the start-- if I'm giving them mealworms, she'll repeatedly miss the worms. When she finally gets one she runs off so none of the other girls can steal it. Her eye color is normal, her behavior and weight are normal, and none of the other chickens are acting funny.

Could this be Mareks, or could she just have bad eyesight? I don't want the rest of the girls to catch it and I don't want to come out one morning to a dead/paralyzed chicken.

I don't think it would be mareks just from poor eye sight. Because I thought that Marek's Disease is mostly paralysis.

I'm not an expert but I doubt it would be Mareks

My Marek's symptomatic birds all peck and miss grain. It seems like an eye-beak coordination problem, they look like they're eating buyt they're not. If you keep checking the crop, you'll find it's never full, and your bird is getting thinner.

It may not be Marek's, but mine have all done it till they died.
