First I did a search on BYC to see what others have had this problem. My rooster all of a sudden can't walk. He is 3 years old. Three days ago I found him in his pen laying on his side. At first I thought he was dust bathing but something just didn't look right so I went over, picked him up and realized he couldn't stand up. He was fine and on their roost the night before when I went out for my eventing check. I checked him over and couldn't find anything apparently wrong. He is molting so he looks pretty pathetic right now. I took him out of him out of his pen and put him in a cage. He is eating and drinking ok. I gave him some vitamins in his water. He does try to stand up but can't. Right now I put him on the grass in the yard with his food and water. He is laying there eating, drinking and pecking at the ground and every once in awhile he will try to stand up. I checked his legs thinking he may have broken a leg but the legs seem fine. I just don't know why one night he is ok and the next morning not. Any suggestions out there in chicken-land?
