We have a 5 month old buff orpington (named Butterball). This is our first time raising chickens, so we've noticed her strange eyes before and didn't think much of it. However, when we let the chickens out into the run she makes a LOT of noise and doesn't come out. When we move her outside she doesn't peck or walk around, and continues to make a lot of distressed sounds. She also doesn't roost and sleeps in a corner of the coop. We moved her back into the coop tonight when it was beginning to get dark. We watched her through the window...she walked along the wall strangely looking at it as if searching for a way out, and then tried to fly straight up, smacking her head into the beam a couple inches up on the wall. We moved her back with the other chickens who were pecking at some food on the ground and she simply walked into the others and ignored the food. So, we're thinking she might actually be blind and are looking for confirmation. The white in her eye is not a glare or effect of the lighting - it's what her eye really looks like in person.
