Once you decide she is broody enough (including being on the nest all night), and you want to "go for it", I would suggest REMOVING whatever eggs she is on at the time, and REPLACING them with a set of all-new eggs. That way the hatch will be pretty well synchronized. I've lost eggs/chicks by not doing this, don't learn the hard way like I did
Good luck, have fun,
