Hello! New here We have a Blue Laced Red Wyandotte hen who is about 8 months old now. We noticed this morning we was walking around oddly, almost like she was drunk/dizzy. Something was very obviously wrong with her behavior. Then we realized that it appeared she was having trouble seeing. Once she was able to find the water she drank, same with the food. When I picked her up her head suddenl lilted downward in a very strange way. I noticed right way her L eye wasn't normal. Almost like the pupil has blown outward. I don't know if you can see in the pics, but the very center of her pupil is light blue. Also, where the reflection is in the pics, there is another odd blacked area of the iris. Her R eye's pupil seems to have the same problem, just much more mild. Once I put her down, she seemed to gather herself and then started to peck at the ground again. We did some research and the closest diagnosis I can get is Marek's diease...but I can't find an Ocular Marek's presentation quite like this. There is no greying of the iris here. We isolated her, but now I am reading it's pretty much too late, if this is indeed Marek's- my other chickens have already been exposed. So my questions are: 1. What do you think this could be? Marek's? Something else? 2. Is it worth isolating her? I'm sure she would "rather" be outside and not cooped inside....and I worry about her being cold at night being alone. *Sorry about the "reflective" pics, it actually appears much worse in person. It almost appears that this eye is bulging out a little.
