We got 4 new Americana chicks all supposed to be hens. When I set them in the brooder I set one in the corner where the heat lamp is. We left for a while maybe an hour or hour and a half. When we came back I noticed that the same chick was still in the same corner. I figured she was just enjoying the heat. After about thirty minutes I came back and she was still standing there. I watched her and found that she only stands there with her eyes closed. She only opens them for a second then closes them again and continues to stand there. When she opens her eyes and sees the food she pecks at it and misses. It's like she can see but still can't see. Is she blind? Maybe half blind? All the other chicks all still kind of scared of us so when you reach your hand in all the chicks run except her she doesn't even notice.
