Now, I hadn't really planned on hatching out more chicks (though I can't say I'd be disappointed if it happened, but I'd need to find new homes for them). How exactly does it work as far as what momma needs? I figured she'd just sit on the eggs in the nest box until the babies hatch, and probably keep them in there a while. Is she supposed to be separated so the others don't hurt the babies?
If the nestbox is ground level there is no trouble with her hatching in it. However, if it is elevated chicks can fall out and then freeze because they can't get back.
Sometimes the mom will protect the chicks from the rest of the flock.... and sometimes all of the flock members are nice to the chicks..... BUT sometimes not!
I hate risking the chicks so separate them for at least a few days and then see if they can be integrated.
