How can you tell a hen is ready to hatch a egg?

Observing a hen right before her eggs hatch, you will notice that she is clucking very softly to the eggs and she is more reluctant to leave the nest for food and water. She knows the chicks will be hatching soon and wants to make sure she is there when it happens.
