I have a chick that is about 3 days old. I noticed yesterday it seemed to walk with its head tilted and almost touching the floor. It will also put the top of its head on the floor (like it is trying to stand on its head). I took it out today and wiggled my fingers on each side of its head and it did not seem to react. Could it be blind? It seems to be eating and drinking fine, but I am worried about it.
