I always leave mine in the incubator till the others are done pipping/hatching or 3 days have went by. They can live for three days without food or water due to the yolk sac. When I do move them to the brooder, I put a shallow dish with marbles in it - lots of them - and ground up food. About a week later I take out the marbles. I've heard too many horror stories of chicks drowning in almost no water.
