I have a duck who suddenly has her outermost toe on each web seperated. The Web is completely torn.I have absolutely no clue how it's happened. There's no wire or anything for her to catch her feet on. There are no snapping turtles because we have kiddie pools. They are not infected. They don't bother her unless she has to run, and I don't think they bother her then, she just can't run as well. Any clue what could have caused this? Anything I could do for her?
