Congrats!! That is very exciting!!!
Now you have to avoid making the mistake I made the first time I incubated. Stop playing with the eggs! lol I know how amazing it feels to feel the little cheeper in there tapping, but once it breaks through the shell you can ruin its chances of getting out of the shell by handling it, or even by having the incubator open.
Once the shell is broken, even by a little bit, the inner membranes become very vulnerable to drying out. If they dry out, the baby gets stuck in place and can't turn in the shell to break its way out. Unless you help it, which is difficult and dangerous at best, it will die in there. Trust me--I lost one this way in my first hatch because I didn't know better and kept taking them out to hear them tapping.
What you need to do is put the eggs in the incubator and raise the humidity way high. You can do this by adding rags or sponges wet with warm water. Then close the incubator and don't open it again until the egg hatches. Even though you hear tapping, it may be another 24-36 hours before the first pip and another 24 hours after that before it hatches (longer if it's duck eggs). So don't fret.
Keeping the humidity up ensures that the membranes don't dry out.
Good luck, and enjoy! Hatching is the best fun in the world.
