Please Help! I gave some buff orpington roosters to a farmer that was looking for some and he called me 6 weeks ago when he had his first round of buff babies hatch from my boys. I have two of the babies that are 6 weeks and two days old. They both have light almost grey eyes. however I noticed one of them has one eye where the pupil is larger and not as reactive to light as the other. They have been separate from my flock with the exception of one time that I took them outside briefly as an introduction about a week ago where they all looked at the babies and one of my hens pecked one of them and that was it, they were right back in the brooder in the bathroom. given the color of the eye and the one off pupil I was wondering if this could possibly be mareks and if so what do I do? They are both acting like perfectly normal 6 week old babies. Is it possible the eye color is just a genetic mutation and they are perfectly fine? If it is Mareks could that super brief encounter have spread it to my entire flock? I am somewhat new to having chickens. Picture is of the same chick just different eyes.
