Hello! I have a recently acquired hen with one flat, cloudy eye. The whole eyeball looks cloudy and sunken in, but there is definitely an eyeball present. I checked online descriptions of Marek's, and that doesn't look likely. She is a new addition to my flock, and I noticed this damaged eye when I moved her in at home. The eye is not swollen or covered in any sort of film that I can see. There is no blood or other signs of trauma, recent or otherwise. The bird is alert and active. She is eating, and even flew away to visit the neighbors the second I tried to move her into the new coop. In the process, she visited at least three different neighbors, perched in trees and on fences, etc - she clearly isn't suffering from the vision loss. While she does appear to be blind in that eye (she likes to keep that side to the wall), she does just fine. Tail up, hopping and clucking and playing. Feathers are soft and shiny, comb red and perky, no visible ulcers, sores or rashes anywhere. Since she is so skilled at keeping her good eye on me, I can't be sure whether this happened in transit or before I picked her up, but I'm fairly sure that it's an old injury. She came with 8 other hens that she grew up with, so I don't expect her to get picked on too badly. Anything I should be worried about, or just keep an eye on her and make sure she's ok?
