McHenry County 4-H Embryology Project

University of Illinois Extension’s
2024 Embryology Program registration is OPEN!  



Thank you for your interest or past participation in the 4-H Embryology in the Classroom Program with University of Illinois Extension. Registration in now open for educator training and eggs orders through February 2, 2024. Supplies are limited so early registration is recommended. 

Program Overview:

What is more fascinating than seeing a fully developed baby chick emerge from an egg? Just three weeks of incubation transforms a seemingly lifeless chicken egg into an active, living being. This interactive project through the University of Illinois Extension’s 4-H program is designed to give your students the opportunity to hatch chicks in their own classroom/learning environment. 

During the 21-day incubation period, students learn how to prepare eggs, set up an incubator, record progress, turn eggs, and test eggs for fertility. The project aligns with both Next Generation Science Standards (NGSS) and Common Core Standards

For more information, go to 4-H Embryology & Incubation:

How it works:

  • 4-H provides online training, classroom resources, and egg-ordering services so that educators can bring embryology to their classrooms. (educators can earn up to 2 PDH)
  • Educators attend training, provide program equipment and supplies for their classroom, teach and oversee the program for their students, and provide participant information and program evaluation data to the 4-H program.
