Agree with that. She'll be fine, just check the foot for a few days.
In the future, should you have issues with a nursing kid, MILK the doe! This will keep production up. Right now, is she getting grain? That will help keep the production going better for a while. Plus, with only one kid, she won't need to produce as much. As you probably know, it's a lot of supply & demand.
There's a reason people bottle the kids -- production by milking.
