Bird sits on broken eggs

Instinct and hormones. If you immediately pull the eggs, she will lay more. If you leave them in, she will sit on them until, either they hatch (which of course they will not) or until they are supposed to hatch and the she will abandon them, which generally takes about 30 days before she gives up.

The real question is ? why did they get holes? Well, their nails may be too long or sharp; they may have a nest box that is too small; the may not have enough nesting material or the right kind of nesting material. They could also have been disturbed when entering the room and they could jump down into the box and damage the eggs.
