Dandy's mom

My Dandy lays an occasional egg that's got a soft spot in it, but never had one without a shell. (She's also never laid more than 1 egg a day) You want to make sure she doesn't get egg bound if the shells are soft or missing completely.2 in one day and 3 another day?? That’s not normal. Has she ever laid good eggs or is she just starting to lay? Are those her first eggs?
I’ve never gotten a shell-less egg from a duck, and only an occasional shell-less chicken egg, and those were always brand new layers and were never any issues. But if it’s lots of eggs, that could indicate a problem.
