the downside to her being broody is that she won't produce, and some won't get off the nest to eat/drink. Just keep an eye on her
I've seen people say you can put them in a pen with a wire bottom and give them a few days (with food and water of course) to try and break their broodiness, but to me it's their natural behaviour, and if you can deal with one less egg, maybe just let it run it's course
