Hi I have been hatching eggs for 10 years now. I'm using GQF sportsman incudators and hatchers. I keep them all at 99 degrees. I don't even worry about the humidity
because it is always humid next to Lake Michigan and I don't use the wicks they say to use. When the temperature goes over 90 degrees here in Michigan then I run into problems
because then my chicks come out early and some of them die after a week and some in the shell. I raise chickens,turkeys,quail,pheasants,guineas, and partridges. I also hatch peafowl
eggs, ducks, and geese for people. So, be carefull about room temperature. To high or to low can really make a difference.
GOOD LUCK.
