If it is just one chick though, I would leave it with momma. The chick will be more flighty but it won't get lonely by it's self when it's human parents have to sleep and do human things. I know when I borrow my broody's chick she has terrible separation anxiety and will puff and cluck until I come back out with the chick. I'm sure she'd get over it when her chick doesn't come back after a few days and get reset so she won't take it back. In addition when you go to reintroduce the chick when it grows up (at about 16 weeks old), the flock will treat it as a stranger and not take it back without fuss unlike if momma hen shows everyone it is family. Still some pecking if it grows up with momma but much less. My broody cares for her chicks for about 8 weeks.
I've raised single incubator chicks and it was ok for the first two days... but then you get the constant screaming for attention and if they can't see you they start to chirp. I took it's heated box with me everywhere and had to set it at my feet so it could see me. It was kind of a pain. I say just let momma raise it because then she does all the work, the chick will be wiser to the world, you don't have to integrate it, and you don't have to deal with a lone chick crying all day and night that it can't see you. Just put food and water low enough for the baby to get to it.
You can go ahead and bring it in though if you want. Either way will raise a chick.
