I have to disagree! there is a chance now that the op has already messed with them he needs to wait till she has the rest and remove them they will not die just because they are not on her back he will have put them in a container with a slightly moist paper towl and heat and wait it out and when they molt try to feed prekilled crixWhen scorpions are giving birth there is one very simple rule;
leave them ALONE. and leave them for a week or two afterwards as well. NEVER remove them from the mother, they will die.
