Day 1: The Journey Begins

-----------------------------------------------

Before the Egg is Laid:

  • The egg is fertilized.

  • The zygote divides and begins to grow.

  • The cells segregate into groups of specialized function.

  • The embryo nearly stops growing between laying and incubation.

During Incubation:

  • The area pellucida and area opaca of the blastoderm develop.

Major events:

  • 18 hours: The alimentary tract appears.

  • 19 hours: The brain crease begins to form.

  • 20 hours: Somites appear.

  • 21 hours: The brain and nervous system begin to form.
