A newly hatched chick typically flares around in the bator and sleeps quite a bit. As long as the chick is on its belly, it should be fine. But they do occasionally get flipped over and will struggle to get back on their tummy. Unless it is on its back for quite some time, I wouldn't worry. They can take quite a few hours until they start running around, depending on the chick.
