Make sure you've got some cuttlebone in her cage cos she'll be using a lot of her own calcium to make the eggshell and if she runs low she could get egg-bound where her internal muscles get so weak the egg will not pass down the oviduct and this can kill them. Also be careful when feeling to see if you think she has an egg cos if it breaks inside her this will kill her too.
If she lays some eggs - maybe one every other day or so - leave them with her, she'll sit on them as if they were fertile eggs. Make sure she gets off them to eat and drink. If you remove them whenever she lays them she'll just lay more. After a couple of weeks she'll probably abandon them and then you can get them out and throw them away
