It’s Chicken Time!
Exploring Life Cycles with Ground Education
Embryology is...
the science that deals with the growth & development of an embryo to a chick inside an egg.
We are hatching chicken eggs!
In nature, a hen lays her eggs in a nest. Then she sits on them.
Why does she do that?
How can our incubator mimic what happens in nature?
Eggs come in many colors
Have you wondered what is going on inside a chicken egg?
Let’s take a look and see...
DAY 1
This is the first day the egg is in the incubator
DAY 2
Today the heart starts beating
DAY 3
Today we can see the eye
forming
DAY 4
Today the wings, legs and tail are growing
DAY 5
Today the head grows bigger
DAY 6
Today the beak and egg tooth form
DAY 7
Today the brain is getting bigger
DAY 8
Today soft down feathers start to grow
DAY 9
Today the mouth opens and claws develop on the toes
DAY 10
Today the beak
starts to harden
DAY 11
Today tail feathers grow
DAY 12
Today the ears start to hear sounds
DAY 13
Today the body is mostly covered with feathers
DAY 14
Today bones in the head and the ribs get harder
DAY 15
Today scales
on the legs and claws harden
DAY 16
Today the chick is absorbing food from the yolk
DAY 17
Today the head turns toward the air space to get ready to hatch
DAY 18
Today is the day we stop turning the eggs and add more water to the incubator
DAY 19
Today the chick is almost done growing
DAY 20
Using its egg tooth, the chick may pip through the shell and start
to breathe.
DAY 21
The egg tooth breaks through the shell and the chick is born!
DAY 21
It may take several hours for the chick to hatch. It is wet and tired.
Welcome to the world baby chick
