Most often, only a broody mother will raise the chicks.
I hatched some out at Easter that I've put with the older chickens out of necessity, and they are getting picked on a little bit... but they'll be 7 weeks old on Friday.
I left my chicks with mommies, in the coop with the others. One hen has 9 chicks, the other has four. One group is 3 weeks old, the other is 2 weeks - and all are doing fine. I think it depends on your individual groups of chickens. Mine free range during the day, so mom and chicks usually go off on their own. I keep expecting to see missing chicks due to predation or one running off, but so far so good.
