I just checked my ducks feet a week ago at most for bumble and they were all clear. Just now I noticed my Duclair Rosie holding up her foot and I found that her middle toe is all swollen. There's no scab, and no sign of injury. Yesterday she was walking just fine. I just lost two ducks after Christmas and I do not want to lose this girl - she is my favorite. If anyone has had experience let me know.
