Sounds like she already has the idea... you need to decide where you want her to spend her brood and prepare it so you can move her (if needed), collect a reasonable number of eggs for her (3-6 is normal for a small banty, maybe 8 if she is big for her breed), mark them and trade them out for those she has and then mark your calendar.
Edit to add... remember that overloading a hen with eggs can cause those left around the outer edges to be cooler and alter development rate, cause birth defects or difficulty hatching, even if she frequently shuffles them to try to keep them warm it may still cause a staggered hatch or cause early quitters in otherwise viable eggs. Be reasonable on the egg numbers to reduce the stress on the hen both before and after the hatch.
