Mire, just spritz the egg with water after 10 days. In nature, geese stay locked down on nest for the 1st couple of weeks, but then will take daily breaks that last longer as they get closer to hatching time. During their break, they will take a quick bath and return to nest while wet, then preen themselves standing over eggs, causing water to drip onto eggs before laying back down on eggs. Paulla, hey friend. Good to see you again!
