She has been broody for about four days. If she is staying on the nest at night and acting "broody" during the day I'd consider her committed and clean it out at your convenience. She might sit there the whole time or she might hop up and run out to eat, drink, poop, and such and return later. I would not expect her to damage the eggs in any way.
Before they are committed they can break from being broody by scaring them or messing with them, but once they commit they flip a switch. It's hard to break them.
