Avian Embryology

 Most children are fascinated at the miracle of life.   The avian embryo is an amazing and exciting project that allows children an opportunity to see the miracle of life.  In only three weeks, a small clump of cells with no characteristic features of any single animal species changes into an active, newly hatched chick. A study of this transformation is educational and interesting, and gives us insight into how humans are formed. 

Several Universities conduct embryology projects and have website designed to help students, teachers and parents with the lab.  We us the following websites for our baby chicks.  If you know of more web sites about Embryology, please send them to the email address below.
