Hello! I have a cuckoo marans hen that hatched two chicks about 8 weeks ago. One of the chicks has always looked smaller, and kind of puny. About a week ago, I noticed that the small chick's eyes are milky and bluish. She has to search to find food and water, often missing. I don't know if her eyes have always been this way, or if this is a developing condition. Neither mom not sibling show any sign of illness. This chick is energetic, and shows no other sign of trouble, except for the small stature. I have never seen this in my flock before. Any suggestion as to what could have caused this, and if it can be reversed? All input will be welcomed! Thank you!
