Can you feel more than one egg?
Like any snake that is egg bound you really don't want to delay things, I would give her 48 hours, in the mean time try soaking her.
It is possible that the egg will need to be aspired which can be done by a vet or at home depending on your experience.
If there are more eggs and the first one does not pass or get aspired and the other still not pass surgery might be required.
I had a female this year that was egg bound with 32 slugs, first 2 had to be aspired before everything could pass.
