Mindy Heaston teaches 3rd grade at Graham Elementary in St. Paris, Ohio. She says:

We took this video last year of our eggs hatching to help our students see the process after hours. The chicks were hatching early morning and late evening, and my students were so upset that they were missing all the action! Our solution was to record the hatchings.
