many chicks are very tired after hatching as well, and it can take a couple of days to start bopping around.
If your chick can hold its legs together I would say it is just resting, and I would check on it in a couple of hours to see if it is walking around a bit.
If it looks lethargic I would give some sugar water, and if it has a spraddle leg you can treat it with the method in the link above.
