It is critical that you stop turning/rotating eggs 3 days prior to incubation.
The chicks are positioning themselves for hatching.
Step 8: Test Egg Fertility
Fertility testing is done to make sure that embryos are developing proper-
ly and to test that humidity conditions are acceptable. Fertility testing
should be conducted at two different times:
Testing is done by candling all eggs in the incubator. A candler can be
made using a shoe box or can. Make a hole with a diameter of about
25% the size of the egg (about the size of a quarter) in the top of the box
or can. Set the egg on this hole. Now place a strong light source (a
mechanics trouble light or flashlight will do) under the box or can. Light
will pass through the hole, into the egg, so that it is illuminated.
• If you observe a cloudy spot or mass, then
a live, growing embryo is present.
• If the contents of the egg allow light to pass
through it uniformly, then it can be assumed the
egg is not fertile. Remove it from the incubator.
Some of the embryos that looked healthy during your first fertility test
may have weakened and died by the second fertility test. These eggs and
any eggs that show signs of blood spots should be removed from the
incubator.
Step 9: Hatching Eggs
When you have 3 days remaining until hatch, stop turning the eggs.
If you have an automatic turner, unplug it, and remove it from the
incubator. Carefully place eggs on the wire screen.
Remove both red vent plugs from the top of the incubator
to increase ventilation.
Increase the humidity level (see step 4). This allows the chick to rotate
freely while breaking the shell during hatching.
Do not open incubator except to remove chicks. Chicks can be removed
from the incubator when they are completely dry. Some chicks may
hatch late, so continue to run the incubator for a few extra days beyond
the normal hatch period.
*For more information on incubating, consult your local library or the World Wide Web.
Step 10: Post Hatch
When chicks are removed from the incubator, they must have a place that
is warm and dry. Please consult your library, internet, or local
hatchery for information on brooding, feeding, and watering.
After all chicks have been removed from the incubator, rinse the
bottom with anti-bacterial soap. Do not scrub, as this will cause
damage to the incubator.
The Automatic Egg Turner base and trays can be washed in a dishwasher
after the egg turner has been properly disassembled (see below).
Washing the Automatic Egg Turner
Disassembly:
Place complete Automatic Egg Turner on
a flat surface. Slide power cord horizon-
tally to remove from notch in base.
Loosen two screws connecting the motor
to base and remove. Slide motor upward,
releasing the white plastic lever from T-
bracket of connecting rod.
Turn connecting rod so offset arms rest in
a horizontal position and egg trays are
vertical. Lift offset arm to release con-
necting rod from notches.
Lift individual egg trays by offset arms
while still in a horizontal position from
offset arm notch in base and pull slightly
to release the pin from the corresponding
hole in the base. Repeat with all six trays
until you are left with an empty base.
Place egg trays and base in dishwasher,
run and dry.
