I have a chick that is 8 days old. last night I noticed that she has silver pupils. She can see because she knows where the food is and eats. She pecks at small things on the ground that a chick that could see would do. She can drink water as she can also find it although it takes her a bit because of her hock joint out of place. The silver looks like it is in the pupil not on top like a blind animal would have. I have a rabbit that cant see the gray is on the top outer part of her eye not in her eye. My chick has had these weird eyes seance she hatched i just did not know they were gray till last night. But I did know they were different from the time she did hatched I just did not look at them till last night.
