All ducks can suffer from joint issues. A crate to keep her quiet might help? How old is she and what feed do you feed?I only mentioned because you seemed to imply she was a meat bird and her weight was the issue. She has been limping for quite a while now; if i were to guess at least 3 weeks to a month, which is why I also mentioned she was limping but seems to have gotten worse. Do you have any tips for reducing the inflammation?
