Her behavior will tell you when she's expelled all of the rest of the egg remains. It may be a shell-less egg and you won't see egg shells, maybe just a twisted membrane. She will behave much more normally as soon as she gets all the egg out.
Be aware, though, there may be a second egg hung up in there. Often, two yolks are released consecutively, not the same as a double yolk egg. These come down the oviduct in close succession, slowing the process so one can get stuck. It doesn't help that there isn't enough calcium in the shell gland for two eggs, so they can be one or both shell-less, further complicating the process.
As I said, you will know by her behavior when she's finished getting all the egg material out. She will be chipper and hungry and most of all, her poop will be normal and she will stop losing fluids out of her vent.
