my broody hen just killed one of her chicks...

If it's a first time Mama, I'd give her a second chance but it the trait (killing hatchlings) continues, I would not allow breeding due to genetics. I wouldn't want that trait continuing in the offsprings. Either eat the eggs/her or rehome IF breeding is your goal.

Is she separated from the flock during this hatching process?

no, for some reason I thought it was a good idea to keep her in with the flock. I'm starting to think one of the chickens killed the chick but i'm not too sure

It's always best to separate out a broody. Sometimes I just put a fence around them. Other birds will kill chicks, and possibly eat them. Other birds will also break and eat eggs. There's a reason when given a choice many hens will make a secret hidden nest away from the flock if possible.
