Have you gone to the learning center and read up on hatching?
Depends on your type of Incubator as to what the temps should be.
Still Air incubators - 101 to 102 range nothing higher.
Forced air - 99.8 to 100
Humidity level ranges 1st 18 days 40 to 50% I keep mine on the low end of 40% for my house.
Last 3 days 60 to 70% range.
I only candle 3 times day 7, 10 and 18. Candling in the first week of incubation can ruin hatches, thats when they really need to rest and grow. I only candle from the Big end down into the egg I think handling too much can make the eggs quitters.
If I hand turn I do it 3 times a day.
Bump your humidity for the last 3 days and no opening the bator. Last thing is Patience!
I also keep a journal and take notes of what my temps and humidity have been for hatches.
