Hello all. I've been given a cygnet to rehab. I've been told it is less than a week old, mute swan, still has egg tooth. It could not follow the momma so it was abandoned. I believe it has splayed leg because it cannot walk. I scoots around a little, usually in a circle to the right. It will not eat or drink on it's own. When I put it's bill in water it usually shakes his head. I put him in very shallow water and he drank a bit on his own but still no food. Feeding it 19% protein, non medicated starter crumbles. I've raised ducks and geese but never a swan. What can I do to help this guy survive? What is different about swans with their food and how they eat. Isn't it different than geese?
