Hi.we have a gosling with a swollen knee joint and foot. It was ok 3 days ago, but has only been exposed to concrete to walk on for the last few weeks. I sell poultry at my work, and this little one was ok a few days ago. I have bought it home hoping that we could do something to help. I will call the gosling Lucky. Lucky has been eating and drinking well and pooing well too. we have given her a couple of swims in warm water and the swollen leg moves to paddle. We have to towel dry Lucky as she cannot dry her feathers/down on her tummy. We have placed 2 rubber bands around her legs to keep them together. the bands are not tight at all. Any suggestions anyone? we are feeding her turkey starter for extra protein.
