Temp really needs to be 99-100, @ 98* you may have slow hatchers or other problems etc... but humidity is too high in my opinion. Does the incubator have a fan? 52-54% is good for lock down. I only incubate dry. The humidity fluctuates naturally . Mine is @27% right now with no water. I have seen as low as 16% and as high as 34%. THIS METHOD WORKS GREAT FOR ME !! JUST GIVING MY OPINION !!Ok I borrowed a medical thermometer from a friend, I couldn't keep it though. So the digital read out at 97degrees and the gqf one was at 100, and the medical one read somewhere between 98&99! Humidity is staying between 52%-54%! So since I could keep the medical thermometer, I'm gonna use the digi thermometer and add a degree??!
Please try out a test batch...maybe your own eggs.
Good luck
