I am 100% sure she is blind. She has not ever pecked for food, can’t find her way to the water. She has cataracts over both her eyes. She whisper-peeps to find her friend but tends to stay in one place and not walk around (she CAN walk though!).Chicks don't need food or water for the first three days of their life as the yolk sac they've absorbed provides nutrients. This is why the USPS can ship day-old chicks. Your chick's lack of enthusiasm for eating might be due to it's not hungry yet.
Are you sure it's blind? Have you tested its vision or just going off the reflective nature of the lens? How is its behavior in the midst of other chicks?
I know chicks don’t need food or water for up to 3 days, which is why I wasn’t panicking on the second day when I realized she still hadn’t figured out how to peck. Yesterday I started syringe feeding her with raw egg yolk and wet chick feed, and filling her crop several times, then showing her how to guide her beak down the water container to find the water at the bottom. She’s been assigned a bantam chick as a guide chicken (Toph is full size but is smaller than the bantam chick, Katara, of the same age, because Toph hasn’t grown yet since she hasn’t been eating much). It’s going ok so far.
