I certainly hope that she is fine. I don’t think there is anything to do if she seems to see normally.I do not see any difference or difficulty in her eating and pecking behavior. She was not vaccinated. She is one 3 chicks that hatched from our own chickens. I'm not really sure what to do at this point. There doesn't seem to be any issue with the pupil. Just this change in iris color as if they are slowly changing.
That’s good. Hopefully it’s just an interesting eye color. I would be cautious about selling/giving away your chickens, but I wouldn’t worry about it otherwise unless she starts to show Marek’s symptoms or one of your other chickens dies of an unknown cause.Yes, both her pupils react to the light. I just checked to be sure.
