how strong are the eggshells?
However strong they were when she started, they'll be weaker now (this happens naturally and progressively during incubation), and if they weren't very good to begin with, they may be breaking accidentally, and then she's eating whatever spills to clear it up and try to prevent the rest of the clutch getting compromised.
