My duck Purple Bill, has had a swollen joint or what I call the elbow for almost 2 months. She is hopping around and using her tail to help balance herself. When I first noticed it I took her to the vet, he didn't believe it was broken, but x-rays would be needed to be sure. Because x-rays are so costly he suggested giving her a shot of antibiotics that release over a two week period. So thats what we did, and $147.00 was paid and we were sent home. 2 months later, she is no better but no worse either. I feel bad with the weather breaking and the snow melting all the other ducks are starting to run around again and she tries but gets tried hopping around quickly. She is eating and drinking normally and laying. The joint is still warm to touch and the swelling is soft and lumpy. I have thought about putting a split on it, lancing it, wrapping it, or should I get more antibiotics?? Not sure what to do.
