Humidity Scale

my duck egg will soon hatch, but my level of humidity has broken. Is there another way to save the humidity?

You do not necessarily need to keep track of it. You must have water in the incubatgor at any time. I have hatched many never kept track of it. Add warm water to the water rings. and three days before hatching, you need to stop turning the eggs, then add moisture either by adding additional moist sponge placed around the eggs.
