My white Cochin chicken is 3 months old, I hatched him myself. I went down to the coop and noticed a little blood, very little, on the ground so I checked him over but couldn't find anything. when I picked him up he started drooling profusely and when I put him down he stumbled and couldn't walk and then seem to catch his balance. He isn't drooling anymore and can walk now but he is not himself. he is standing in just one spot snd not really moving. Any help here??
