I just started the incubator on Sunday the 21st - so I will know in a couple weeks . HOPING to do better. My broody should hatch hers next tuesday-ish. She's been pretty good about keeping her nest up, so I'm hoping she does better than me. I'm trying to figure out what to do with her as she is in the coop (general population) and I want to protect the chicks. I'd hate to move her and have her abandon her nest. Might just put a few chicken wire panels around her when it gets to be hatching time, then move her and the chicks together somewhere safer.
I am no expert and my flock is not even full grown yet. But my neighbor has a small farm and I go over everyday to watch his chickens. I've kept a close eye on all his broody hens. The 4th batch of spring just hatched this past weekend. After the hatch is finished, mama hen jumps down out of her nest box, the chicks follow and they follow her around, wherever she goes. None of the other chickens bother the chicks. I've never seen one problem with any of the mothers and their babies. Some of the other hens AND roosters will even take turns babysitting the new chicks or letting them warm up under them! Have you considered just letting mama introduce them in with the main flock?
