Might I suggest you chop up some fruit, enjoy it over vanilla ice cream, prop up your feet, and chill. Relax! I know. Easier said than done.
Hens have been doing this for thousands of years. I'm not going to say that all of them do a perfect job, but I will say that almost all of them do a real good job. I figure mine usually do a better job than I do.
It could easily take a couple of days for the eggs to hatch. The chicks can go three days without eating or drinking, so Mama is not under a lot of pressure to come off the nest too soon. She can wait until she thinks all the eggs that are going to hatch will hatch. She will come off the nest when she is ready. If the hatch has just started, I'd guess that will be tomorrow, but I really don't know when she will bring them off. It could be late today or maybe even Tuesday.
She does not set down real hard. She will raise up enought to give them the room they need to hatch and move around. I've had the chicks climb up between her wing and body to snuggle really close. You might see some climbing on top of Mama or walking around the nest. Or they may stay hidden under her the whole time. It is an exciting time, especially your first but believe me later ones are too, but the best thing to do is to leave her alone and let her do what her instincts tell her to do.
