We are talking about chickens, right? We'll be hatch buddies since I just put four eggs under a broody hen last night!
Other than what's discussed, it goes like this. Chickens take 21 days (or so) to hatch. For the first 18 humidity can be low, I kept mine around 40% but didn't have to add water since it's so humid in NC where I live- called dry hatching. You should mark your eggs with an x on one side and an o on the other, or something else along this lines. This way when you turn the eggs three times per day you can tell if you've already turned them. On day 18 you raise the humidity to 60-70% by adding water and if your eggs are in an automatic turner you remove them from it. I put my eggs in cupcake papers to help with clean up. From day 18 until the chicks are dry you don't open the incubator and you don't have to turn the eggs any more. This is the stage usually referred to as lockdown. Chicks can be in the incubator for up to three days after hatch since they are still absorbing yolk and are usually not hungry. As soon as you do remove them to the brooder, give them access to food and water cause they are like teenagers at a pizza party!!
If I've forgotten anything or accidentally misspoke hopefully someone else will come along and correct or fill in the blanks. Good luck and keep us updated!!
