I've not had good luck moving a broody. Usually they end up breaking so I generally figure out how to separate them where they set or I mark eggs and remove extras daily. Than after she hatches I move the brood into a small temporary pen.
I generally fence off the mom and brood right inside the coop, and I release chicks and mom under supervision at 1-2 weeks of age.
You will need to set up a pen so the flock can see them for a few days at least before try to mingle them again. Chicks under 2 weeks sometimes aren't strong...
