5. PERIODIC CHECK OF EGGS DURING INCUBATION
(CANDLING)
The candling is a technique that allows to check if the eggs are fertilised or not and to assess the development
of the embryo.
This operation should be carried out in a dark room, using a strong beam (e.g. an egg tester) on the egg. It
shall be repeated three times during the incubation cycle, starting on the 8th/10th day, at intervals of about
one week according to the type of egg. The unfertilised eggs or whose embryo is dead must be discarded.
The candling is a delicate and complex operation that can lead to eliminating fertilized eggs by mistake. Since
it is facultative, if you are not experienced we recommend proceeding directly with the incubation.
6. HATCHING AND BIRTH OF THE CHICK
The following operation is very delicate and should be executed quickly to prevent the eggs from cooling. We
suggest that two people perform it in order to reduce the time as much as possible.
Three days before the expected hatching date:
a)
b) Remove the eggs from the swinging tray and place them gently on a blanket or on a specific egg tray.
c) Remove the egg tray (foto O).
d) Put the supplied hatching grill floor (removed before the beginning of the incubation) into the base of the
incubator, ensuring that its two plastic tongues cover the internal side of the water openings (photo P) so
that the chicks will not fall into them and drown.
e) Distribute the eggs on the grill (photo Q) and close the lid.
f) Fill both basins with lukewarm demineralized water.
g) Set the temperature to 37,2°C (see instructions on page 17).
IMPORTANT
During the last 3 days:
- Do not turn the eggs.
- Do not open the incubator unnecessarily as the necessary humidity and heat for the hatching would
escape, causing the death of the chick inside the shell. It is recommended to open the incubator only after
having unplugged it, maximum once a day to extract the dried off chicks.
Keep the newborn chicks in the incubator for about 12 hours. They can stay inside the incubator for 3 days
without drinking or eating without damage.
Once the scheduled incubation days are over, let the incubator work for 2 or 3 days longer to allow any late
chick to hatch.
7. FIRST DAYS OF LIFE
Put the chicks in a draught-free room provided with the necessary heat and light where they can be fed and
watered.
TIPS: you can use a carton box big enough to contain a drinker and a feeder (min. 50x50 cm) and cover its
bottom with newspaper sheets that will require daily renewal.
For heating, you can hang a reflector with an infrared heat lamp at approximately 20-25 cm from the floor. The
temperature can be adjusted by changing the height of the lamp.

INCUBATOR WITH EGG TURNING UNIT SEMI-AUTOMATIC INCUBATOR
Stop the egg turning unit by unplugging it when
the eggs are in a vertical position: this will facilitate
the removal of the egg tray after the eggs have
been taken out.
Remove the metal handle from the front of the in-
cubator (photo N).
INCUBATOR WITH EGG TURNING UNIT INCUBATRICE SEMIAUTOMATICA
To remove the egg tray simply lift it, pulling it out
from the tongue of the egg turning unit.
Note for the following cycle:
Be careful to reinsert the egg tray correctly when
you relocate it. If after several incubation cycles
you notice that the slit - where the tongue of the
egg turning unit is inserted in - is too large, swap
the row with another of the tray.
Remove the egg tray.
Note for the following cycle:
Be careful to reinsert correctly both the egg tray
and the handle when you relocate them.
