What would make an otherwise healthy cockerel suddenly have trouble seeing. This morning I noticed that one of my white orp cockerels was hiding. When I went near he did evrything in his pwer to get away hitting the fence,walls, tripping over the feeder and waterer. I picked him up and he was making this terrible squealing sound like he was terrified. I put him back down and put some ffod and water in his hiding place. He stood there most of the morning in one spot. He didn't move until someone or something came near his hiding spot. I am convinenced he cant see. I put him in a separate pen for the night but I don't think he can find the food and water. Any ideas on what would cause this so suddenly. He was hatched May 31 and has been healthy until now. He get medicated chick starter. His poo is fine. no othr symptoms at all. His eyes do not look cloudy or anything but when I waved my hand near his face he didn't move. Any help would be appreciated . Micki
