Other than her stomping on the eggs and breaking them using a real hen is just like using a lectric hen; candle them every so often and discard the bad ones, and when they start pipping don't pick her up to look every 10 minutes because that is just like opening the lid on an incubator during lockdown. When they hatch don't mess with them. Let them sit in the nest for 24 hours just like you do with an incubator, or just leave them alone-they'll jump out of the nest when they're ready to face the world, usually 1 or 2 days after they hatch.
Also she won't starve herself to death. She'll get off the nest at least once a day to eat, drink, roll in the dirt and make a HUGE poop.
