I noticed several weeks ago that our 11 week old BO pullet couldn't see very well. If I hold out small treats in the palm of my hand, she pecks just in front the treat and only occasionally makes contact with the food. She is currently living with an11 week old EE pullet. They spend their nights in a dog crate and days out in our chicken run. I am in the process of introducing them to our 3 adults hens. She is finding her food and water fine and seemed healthy otherwise. A few days ago was her first day free ranging with the big girls and I noticed her right eye was partially closed. I don't see anything else different with that eye (no discharge or swelling). Any ideas what could be making her squint and have poor vision? Thank you!
