few years back my broody hatched eggs and there was one left, day later she rolled the egg out of the nest and when i candled it, it had died, mamma knows best. If she's going to look after them, its easier to leave them with the flock, mamma will sort out the other chooks but you will need to have food available for the chicks as Chickassan said thats a good idea. Might also be a good idea to make a separate nest/broody box inside the coop for them cause sleeping and raising chicks in the egg nesting box will get very poop messy through out the night and will be a big clean up for you in the morning.
