Everyone does it a little differently. Once the eggs are pipping (or are cut), I put the eggs on damp paper towel in the incubator, so that I don't have to wash off babies.

Then I set them up in one tub all together until they have their first sheds (and I usually keep that tub in the incubator with a small dish of water). Once they've had their first shed, I'll separate them into individual tubs in the baby rack.

A week after shed, I offer their first meal.
