Congratulations!
I'm not an expert (hatched twice with a broody for the first time this year), but it has been a good experience. The only thing I'd be concerned about is the eggs will be hatching about October, so the chicks will hit 6 weeks in November. If the broody chooses not to stay with the chicks for the full six weeks (my one did, I don't know what my other will do) you might need to provide supplemental heat.
You will probably want a separate place for your broody and the chicks. Here's what I did. My broodies are both bantams. I cut an opening in a small moving box from Lowes and put it in a wire dog kennel in my shed. I moved her into the box at night with some fake eggs. After I was sure she wasn't going to break because of the move, I got her some real eggs. The hen brooded in the box. I put food and water in the box while she was broody and threw her off the nest for her daily constitutional. She and the chicks lived in the kennel for the first five weeks then I fenced off under the coop and let them live there for another few weeks. My second broody I put in my new bantam coop and she brooded in the nesting box there.
(If you use horizontal water nipples, you don't have to worry about providing a chick waterer too, the broody will show the chicks how to use it.)
Integrating the chicks has been a bit of a pain. My coop and run aren't very big. I put a roost in the run, so right now the pullets live up there most of the time. I've heard things improve once the pullets start laying, so I'm hoping that happens soon.
I made a timeline of what happened when, so I'd know for later. It's only one hatch, but might give you an idea of what you might expect.
I really like hatching so far though. Good luck.
