Embryology is the study of
growth and development of
embryos from fertilization to
hatching. It is also the most pop

youth can gain from observation
and the study of life.
The bird egg is ideal for this
study because the development
takes place outside the animal

incubation period (important for
youth). The level of difficulty can
be varied according to capabili
ties of the students involved.
Knowledge of embryology can
also be used by hobby and com
mercial poultry producers to
evaluate hatchery management.
By breaking out the hatch
residue one can determine when
the embryo died, possibly why
they died, and how a change in
management of the equipment
or handling of the eggs could
improve reproductive efficiency.

tion, small groups or family 4-H
groups could also accomplish
this process by contacting their
local extension agents. The
agents and offices have resource
material that can guide a study
of embryology at many levels.
The fijfst question is “where
can I get the eggs and equip
ment?” The information is
included 1 ! in the manual
“Beginning of Life.” What’s
required is an incubator that
can maintain 99.5 to 101.5
degrees F, fertile eggs, and time
to manage and study the devel
oping chicks.
, Fore thought in deciding
what to do with the chicks that
hatch is important prior to set
ting the eggs in the incubator.
Placement of the birds in a good
home and humane disposal of all
remaining embryos is essential
and is discussed in the manual.
After obtaining fertile eggs from
a reliable source (eggs from the

grocery store are not normally
fertilized), the eggs should be
maintained in a manner to pro
tect them from conditions that
would cause early embryonic
mortality.
Hatching eggs should be held
at temperatures between 55 and
65 degrees F at 70 to 80 percent
relative humidity (RH).
Temperatures greater than 68
and lower than 40 degrees F can
cause some embryonic death.
Storage of hatching eggs for less
than 10 days is advisable - opti
mal storage time is three days.
After storage, eggs are
warmed to room temperature for
2 to 3 hours before placing in
the incubator. Incubation is the
process of maintaining environ
mental conditions favorable for
development and hatching of
eggs. The most critical incuba
tion factors are temperature,
humidity, ventilation and turn
