One of my geese has a limp too. The problem seems to be in the ankle joint, although there is nothing to see or feel. We have kept her confined for a week and it IS improving. It is considerable work to find and cut enough greens for her, especially this late in the season, but if rest helps her, it is well worth it. Hope this helps.

That has happened manytimes with our Muscovie, it always seems to get better even though it an take several weeks to show any improvement. She got so bad at one time she couldn't walk and we had to carry her around so she could be with the other ducks.
