I have three Frizzle eggs locking down this morning in a still air. The trays are full, the paper towels on the grate are damp from the water underneath, and the eggs are rocking. What is the optimum temp/humidity and can I set the eggs directly on the damp paper towels? I have them in an upside down styrofoam egg carton top now. Is that better than directly on the paper towels?
