So got my mini incubator today ( after ordering a month ago ) and since it came out of China, you guessed it, no instructions for use. Soooooo>>>> I did research on line and found that it needs to be set to 99 degrees and 50%-55% humidity. But, where I fall off into the abyss is when filling the unit with water, there isn't a "fill to here" line so do I fill it and cover the holes that are under the egg holder or just under that point.....so confused. and the eggs are coming on Monday. Please help this new chick out. Many thanks.
