The perfect accompaniment to a classroom hatching project, this video helps students envision what is going on inside a fertilized, developing egg even though the egg doesn't appear to change from the outside. Detailed images of a chick's development along with a summary of milestones that the chick has achieved on or around each day provide an in-depth look at the 21-day hatching cycle.
