Just to let you know that the twitching does not actually increase the heat in the mother's coils. The mother actually has to leave to bask and come back to warm the eggs. She either coils tightly around the eggs or loosely to control the humidity.
If the eggs are left on a hot spot in the cage, they will die.
I agree, separate the BP's. It's best for them, and you want whats best for them right?
