If you decide to separate, remember to roll the eggs inward from all directions when separating. If you notice the shell start to tear work from the opposite direction. I’ve also seen people use dental floss to separate eggs but flossing them apart.
Tip* Keep a few extra egg shells after babies have hatched. If you tear an egg open, wet the already hatch egg, cut a piece and stick it over the tear. The eggs will naturally adhere to each other and seal the hole.
