The neck stretching and beak gaping is normal. Chicks are little pigs and stuff their crops pretty full. They stretch their necks and act like they're yawning. This helps settle the contents. If you see a chick is doing this repetitively, you can help by massaging its crop in a circular and downward motion with your finger. It helps the contents go down and make the chick more comfortable.
