Answer
With the cracked egg, you can try to repair it.  Get some Elmer's glue and paint a thin coat over the crack and let it dry.  Then put it back in the nest.

Females will rarely attack eggs.  They don't distinguish another budgie's eggs from their own really.

Budgies usually lay between three and six eggs, one every other day usually.  They hatch about 18 days after the female starts to incubate, which is usually once she has two eggs.  There's no real way to tell when she's done except watching and counting the eggs.
