A week ago we noticed our drake was walking with his head tucked in. Just assumed maybe he was being bullied by the other drakes. On Friday night we noticed something his one eye was foamy Saturday morning we went to let him out of his cage and found him on his back. He has no balance. Is barely eating or drinking ...I think mainly because he can't balance himself long enuf ... He will take some food,bread and will drink but only with our assistance while he is in his pool . He has diareah and has lost all of his oils He wants to move. When we put him on his feet he tries to take a few steps and falls and within after a few steps and ends up on his back. He does not seem in distress seems very calm None of my other drakes appear to be sick If we is not penned the other drakes try to peck at him. Anyone have any suggestions? We tried Epsom salt in the baby pool. We tried olive oil with bread....it does not appear to be helping tho.
