PROBLEM POSSIBLE CAUSE SUGGESTION
Mortality of embryos after the
second week of incubation
(15 - 18 days)
Too low or too high humidity
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Incorrect arrangement of the eggs
(with the point upwards)
Insufficient ventilation
Dead embryos in the second
week
Too high or too low temperature
during incubation
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Eggs not turned or turned
infrequently
Occasional lack of electricity
Too big air cell (excessive weight
loss)
Undersized eggs (too small) Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Too low humidity during the
incubation phase
Too small air cell (small weight
loss)
Oversized eggs (too large) Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Too low humidity during the
incubation phase
Chicks with malformed lower
limbs
Incorrect temperatures and
humidity during incubation
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Chicks that die before piercing the
egg
Eggs not turned or turned
insufficiently during incubation
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Eggs with a too thin shell
Temperature errors during
incubation
Too high temperature during
hatching
Too high or too low humidity
during hatching
Chicks that hatch early
Small eggs Select with care the eggs to be
incubated, check and correct
the operation of the incubator
especially during the first 15 days
Too high temperature
Too low humidity
Pierced eggs but dead chick
Too low humidity or temperature Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Preheating too short
Early hatching and unlively chicks
with poor immune defenses
Delayed egg collection or the
egg remained for a few hours at
a temperature between 19-25°C
(66,2 - 77 °F). These subjects are
more receptive to the countless
bacterial and viral infections,
present everywhere
Check the management of the
parents, if necessary
check and correct the operation
of the incubator
High incubator temperature
Deformed chicks
Wrong temperature Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Check for hatching egg trays
Errors in egg turning
Small chicks
Too small eggs
Select with care the eggs to be
incubated, check and correct
the operation of the incubator
especially during the first 15 days
Excessively hot incubated eggs
Insufficient humidity
High incubation temperature
Chicks with too little feathers
High temperature Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Insufficient humidity
Flaccid and wet chicks
Too low temperature Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Excessive humidity
Poor ventilation
PROBLEM POSSIBLE CAUSE SUGGESTION
Chick attached to the shell and
dehydrated
Insufficient egg turning
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Wrong temperature
Excessive evaporation of eggs
Too low humidity during hatching
Wheezing chicks
Humidity at hatching too high or
too low
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Badly healed navel
Excessive humidity during
hatching
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
High incubation temperature
Weak chicks High incubation temperature
Dried chicks High incubation temperature
Chicks that hatch late
The eggs suffered a temperature
jump at being immediately placed
in the incubator from the storage
area
It is advisable to let the eggs
rest for about 6 hours inside
the incubation room in order to
preheat them, select the eggs to
be incubated with greater care,
check and correct the operation
of the incubator
Large and old eggs
Too low temperature
Too high humidity
Yolk not completely reabsorbed
Too low temperature during
incubation
Select more carefully the eggs to
incubate and if necessary check
and correct the operation of the
incubator
Too high humidity during
incubation
When the incubation is not successful, it is advisable to break the shell of the discarded eggs and check the
presumable age of embryonic death.
9. PROBLEMS THAT CAN OCCUR IN HATCHING
Sometimes it may happen that the embryo forms, but the chick is unable to hatch, in most cases dying in
the last 3 days preceding hatching. This situation is technically called ‘late embryonic mortality’ and can have
multiple causes. As already mentioned, even before the operating modes of the machine and the modula-
tion of temperature and humidity with the local reality, the secret to obtaining a good hatch lies in starting
with suitable eggs, respecting the indications provided and the weight standards of the breed. Even if the
eggs were selected in an adequate manner but the results do not conform to expectations, the explana-
tion may be found in various other causes, such as inbreeding or dietary deficiencies in the parents, em-
bryonic hypotrophicity, altered oogenesis, viral infections or bacterial contamination. To have certainty about
the diagnosis, it is necessary to contact a laboratory specialized in microbiological analyzes, preferably a
ZOOPROPHYLACTIC INSTITUTE (ZPI), which can also adequately perform a correct autopsy analysis.
10. MAINTENANCE CLEANING AND STORAGE AT THE END
OF THE CYCLE
Cleaning should only be undertaken with the power off and when the appliance is cold.
Do not immerse electrical components in water to clean them.
Dirt can cause damage to the appliance, to the incubation and to the people using it. Make sure both the
inside and outside of the incubator are clean.
At the end of the cycle, thoroughly clean the lower part of the incubator with neutral detergent first, then
disinfect it with a chlorine-based disinfectant or some household bleach. Do not use alcohol or other chemical
detergents.
Thoroughly clean the lid exterior with a soft cloth, dampened with clean water and squeezed out.
The external part of the protection grill of the lid should be cleaned with a soft cloth moistened with a chlori-
ne-based disinfectant or some household bleach. Blow the internal part with compressed air to remove any
feathers dropped by the chicks.
During these operations the incubator and the egg turning unit must be unplugged.
Do not use solvents, diluents and toxic chemicals. Please refer to the chart at the end of this manual for the
list of the substances that would damage the plastic parts.
Allow all parts to dry thoroughly. Place the incubator in a dry place, safe from hits and changes in temperature.
Do not put any other object on top of it.
Do not attempt maintenance on electrical components.
