Feeding a meal might help move things along, not the first time I hear it and I have tried it myself, sadly without positive results.

No suggestion of oxytocin?

While you are waiting I would keep soaking her in warm water and massage her gently, not much you can do until they get a look at her.

My guess when they do if she has not passed her eggs yet they will likely aspire the first one (this is the least invasive option.)
