Congrats on your broody! That is so exiting, I love it when I get a broody hen. They are great fun to watch with their chicks.
How long were you incubating the eggs before you gave them to her? I've heard of hens having a "biological clock" when it comes to hatching eggs and if the eggs hatch too quick, like within a week, it'll confuse them and they may not accept the chicks. But if they still have a while to go it should be O.K.
You can leave her where she is with her eggs, broodies hate being moved and will often reject the new nest. Just make sure she can get out to eat and drink and have a dust bath every day.
When the chicks arrive it would be kinder to let her raise them. Depending on how many you are hatching, you can even add the incubator chicks, or some of them to her. This is easier done in the evening, when she's sleeping. Then just keep an eye on her in the mornings.
When the babies arrive you can leave them and mom with the rest of the flock, but keep an eye on them, in case they attack the new arrivals. It happens sometimes, depending on your chickens, some do, some don't.
Make sure the chicks don't eat layer food! They (and mom) must get chick starter. Don't feed mom layer as she will give it to the chicks and if she's broody, i.e. not laying, she won't need it anyway.
