I'd put them back under her. They may very well hatch anyway. But this is likely to happen again. They will also move eggs from one nest to another, lay their egg in her nest with her in it, break an egg during the shuffling, etc. It's really best to isolate a broody while she is setting. She needs enough space to walk around a little, poop, for food and drink of course, and a dust bath is a good thing.
The first time I let a broody hatch eggs, she was in the coop with the others. I marked which eggs I'd chosen to be hatched with a Sharpie, and I went to the coop several times a day to put the broody back on the right eggs in the right nest, as needed. I don't remember the numbers, but some of them hatched and some did not. Now I have a separate "room" in the coop, with walls of chicken wire, about 5' x 5', where I can house a broody, injured chicken, etc. Once the chicks have hatched, they want to get out with the flock so I let them. A good mama protects the chicks, and I just feed everyone starter or grower or flock raiser. People who often have broodies and chicks often feed only flock raiser, as all ages can eat it.
