I heard, and don't take my word as gospel please, the chicks hatch after about 21 days, sometimes they take a little longer. They can survive 24 hrs on the yolk from the egg, contents, which they eat, after that they should be slowly introduced to chick crumb and water. I'm not sure as to when to remove them, if my memory serves me right I think its between 2-3 days old, not sure. Do you mind if I hang onto this thread to see what everyone else says?
