fowlweatherfriends,
I have a Little Giant but it has the fan... it came with a liner for the incubator... if yours did as well then I have found that adding water to the two inside rings gives me 50% humidity if I keep them filled and then for 75-80% in the final days I add water to the big outter ring as well... also one added note - don't open the incubator after day 18 unless you absolutely have to!! The chicks will be fine while the others hatch and opening it reduces the humidity a great deal more than you would think and can cause the chicks that are pipping to get stuck and die before they can get out of their shells. Good luck and happy hatching!
