you want to separate her @towen91

if she keeps getting new eggs every day, they are going to develop on the day they went under her. so she could be looking at a 4 day long hatching session, which is really not ideal-- the first chicks out will need help from mama, and she will refuse to get up. she will also likely get on to the eggs on day 18 of the first set of the eggs and not get off until everyone hatches, which could mean more than a week of not getting up. that means sick hen, poop in the nest, lots of things you don't want!
a lot of people opt to put their broodies in a dog crate! room to walk off and poop and stretch, but also safe.
the other option you have is to mark the eggs now, and every day maybe at night depending on how she lets you handle her, collect the unmarked eggs. you do run the risk of missing one, or disturbing her too much and breaking her broodiness, leaving those eggs with no mama. those are things you will have to weigh, and none of us can tell you which direction is best for you and your flock! but one way or another, you need to make sure that new eggs aren't being added to the nest.
after that! ha! your hen will sit for around 21 days, and will usually get up once a day for 30 minutes to an hour to poop, dust bathe, eat and drink. if it's really warm where you are, she might get up longer, and that's ok! as long as she goes back! on day 18 she will probably get up one more time and then won't leave the nest until everyone hatches. there is plenty of time between now and then to google everything! which i recommend!
but to start with, here is what i wish i had known, and hopefully others will chime in!
1. dont put food and water right in front of her because then she has no reason to get up and will poop the nest!
2. dust the nest and mama with your choice of bug control (diatomaceous earth, sevin dust, ash, baking soda any of those. look them up, and again, make the choice that you feel is best for your flock! everyone has an opinion on them!). do it again a week later when she's off the nest and dust her again as well, and do it one last time on day 17 or 18. sitting hens are lice and mite targets and it is the right time of year to make a lot of problems
3. if the coop is especially warm, you might want to rig a fan in there if you let her stay. she won't do as much to cool herself off as the rest of the flock will.
4. many people candle on the evening of the 10th day and toss non viable eggs. there are many, many tutorials and blogs and ways to learn about candling online, and you have time to read up on it!
there is probably lots more info! good luck, and congrats!
