MARVEL OF GOD'S CREATION
#8
The Chicken Egg
A fertilized chicken egg is a very
special
creation. Before even thinking about a chick developing in an
egg, it is
interesting to ponder how the chicken manages to get a shell
around that
slippery, raw, fertilized egg. It is a rare sight on the farm to
see raw
egg smeared on the outside of the shell. Have you ever attempted
to put
an egg back into its shell after it rolled off the
counter?
The shell itself is highly specialized.
Each egg
shell has about 10,000 tiny holes or pores. How does that
chicken form a
shell around a soft, messy egg and design the shell to have
porosity?
Put a raw egg in warm water and soon you
will see
tiny bubbles floating up. These bubbles are escaping through the
pores
in the shell. The developing chick needs these pores to breathe.
Evolution requires a need before an organism will change. How
does a
chicken know it needs to make a shell with porosity, and how can
it
manufacture such a shell? The chick does not know it needs the
holes in
the shell to breathe until it dies for lack of air. Of course,
dead
chicks cannot evolve.
Within the first few days after the egg is laid,
blood
vessels begin to grow out of the developing chick. Two of these
attach
to the membrane under the eggshell and two attach to the yolk.
By the
fifth day, the tiny heart is pumping blood through the vessels.
What
makes those blood vessels grow out of the chick, and how do they
know
where to go and to what to attach?
The chick feeds from the yolk with the yolk
vessels and
breathes through the membrane vessels. If any of these vessels
do not
grow out of the chick or attach to the correct place, the chick
will
die.
The chick gives off carbon dioxide and water
vapor as it
metabolizes the yolk. If it does not get rid of the carbon
dioxide and
water vapor, it will die of gaseous poisoning or drown in its
own waste
water. These waste products are picked up by the blood vessels
and leave
through the pores in the eggshell.
By the nineteenth day, the chick is too big to
get enough
oxygen through the pores in the shell. It must do something or
die. How
does it know what to do next? By this time, a small tooth called
the
"egg-tooth" has grown onto its beak. It uses this little tooth
to peck a
hole into the air sack at the flat end of the egg. When you peel
a
hard-boiled egg you notice the thin membrane under the shell and
the
flattened end of the egg. This flattened end, which looks like
the hen
did not quite fill up her egg shell, is the air sack. The air
sack
provides only six hours of air for the chick to breathe. Instead
of
relaxing and breathing deeply, with this new-found supply of
air, the
chick keeps pecking until it breaks a small hole through the
shell to
gain access to outside air in adequate amounts.
On the twenty-first day, the chick breaks out of
the
shell. If one step in the development of the chick is missing or
out of
order, the chick dies.
Each step in the development of the chick defies
evolutionary logic. The process must be orchestrated by God, our
Creator. The impersonal plus time plus chance is not an adequate
explanation for the incredible complexities of life as we
observe
it.

booklet
discusses ten of God's creations and shows how they could not
have
evolved. There are a series of these
booklets.
