Our favorite time of year in fourth grade is spring! For the past five years, we have been fortunate to have the Schuylkill County 4-H Embryology program included in our science curriculum. This inquiry-based program teaches children about the growth of developing chicken/duck embryos, the biology of eggs, agriculture, and the responsibility of caring for the hatchlings. We also learn life lessons as the class watches the chicks/ducklings develop, hatch and grow. This is truly an exciting time for all of us!

Embryology is the study of a growing embryo, from its incubation period, to the time a chick hatches. We use chicken and duck eggs in our program. The picture on the left shows a chicken egg being "candled" to observe the development of the growing embryo.

Did you know?


It takes 21 days for a chicken egg to hatch, once it is placed in an incubator.


The incubator must be kept at a specific temperature with water in the bottom.


Ducks take 28 days to hatch.


An egg must be "fertile" in order to hatch.


You will learn lots more fun facts in our Embryology program this spring!



Our fourth graders take excellent care of our ducklings!
