I set mine at 55-60%, and later increase to 80-85% during lock down. Your incubator should have two large channels for water. Just use one first and later fill them up all. This means in my region all 4 channels or impressions, due to my dry climate. You may only need 2 in Florida. Just don't have it go below 50% or they can bind inside of the egg. I once went down to 20% and almost had a heart attack. Forgot to refill it, and here in the high desert I have to fill it daily. They turned out alright after all. Try to turn them as much as you can in the first week and don't forget to mist them daily with warm water. Some leave the misting bottle in the machine. I don't because bacteria can grow in the water. I simply run hot water in my sink to about 100-110 degrees. It will cool somewhat when you mist it anyway. You do not need to cool off the eggs daily, if you have an incubator with a fan. Without a fan you should cool them for for 10 minutes daily. Set a timer so you don't forget. Also use warm water to refill your incubator. For candling I use a very bright LED flash light. It does not emit heat and therefore not damage the egg. I also never remove the egg out of my turner for candling. The less you handle them the better. I wait until night and shine the light into the egg. Works well for me. You should see some blood vessels on day 5. After that I check weekly. A cheap stethoscope is wonderful so you can hear the heat beat.
