I like dry incubation
so I keep humidity 40 - 45 for 18 days and 65 the las 3 days
60 is way to high
the best thing to do before you put the eggs is
run the incubator without water for 24 hours with the hydrometer inside to get the actual humidity in your house
after you get that reading , add water if needed
add water in small quantity , measure by spoons
add 1 spoon and wait for 1 hour get the reading to find out how much humidity 1 spoon will give you
and this way you keep adding until you get the humidity you want
if your incubator is empty now , open it and dry the water with paper towels and start allover again
if your incubator is full of eggs
open the vents until humidity lowers by itself
hope this helps
