Yes.
Make the nest accessable for any chicks that fall out, but enclosed enough to stop them from doing so, if you see what I mean. The worst problem is when they get knocked out by other chicks or eggs or a restless hen just after or during hatching. Once they've hatched and flopped around exhausted and dried out they will stay under mum, if they can, for 24 hours and she shouldn't move until all eggs have hatched or she's given up on the late/infertile ones.
It can be so hit and miss, but try to maximise the chick's chances. If the hen is very broody, she won't be put off by being moved somewhere safe and shut away from other curious and jealous hens.
