Information Regarding Correct Incubation: Eggs Of All Exotic Birds; Periodic Egg Inspection During Incubation (Candling) - Borotto REAL Series Instruction Manual

9.4 - Information regarding correct incubation:
Temperature to maintain during incubation: 37.0°C
Temperature to maintain in the last 3 days before hatching: 36.5°C
Refer to the following table by keeping in mind that incubation varies according to the species. For detailed
information regarding special species, consult the relative texts.
PARROTS Incubation time
Amazon 24-29 days

Ara 26-28 days
Macaw 26-28 days
Lovebirds 22-24 days
African grey 28 days

Eclectus 28 days

INCUBATION: During incubation, maintain temperature at 37.0°C and fill only one water tray.
HATCHING: In the last 3 days before expected hatching, the eggs must not be turned any longer. They must be laid on the
hatching grid and humidity must be increased by filling the second tray as well pouring 2 or 3 glasses of water at the
bottom of the incubator. Then set the temperature to 36.5°C.
The incubation days table is indicative, it is recommended to leave the incubator on for 2 or 3 days more than the
indicated deadline to allow laggards to hatch.

10 - Periodic egg inspection during incubation (candling)

Candling is a complicated and delicate operation that may result in errors as eliminating fecundated eggs. Since it is
optional, we advise not to perform it if one has no experience and to proceed with incubation. Otherwise, the
incubated eggs may be periodically inspected by candling. This operation must be performed in a dark room using
the egg candler, which is available on the website www.borotto.com, following the table below:
Species
Hen
Pheasant
Guinea fowl
Turkey
Grey Partridge / partridge
Peacock
Goose
Mallard and wild duck
Muscovy duck
Extract the eggs from the incubator one by one and check them immediately. The egg may remain outside the
incubator for 2 minutes at most. With a little experience, and using the suitable instrument, the eggs may be
inspected without extracting them from the incubator. In that case, open the incubator and place the candler onto
each egg. The light beam lets you see the embryo. Never turn or shake the eggs with violence as this would cause
the blood vessels to break and result in embryo death.
1st Inspection: start of the incubation: It is usually difficult to see the embryo because it is encased in the yolk: blood vessels
are visible near the air cell and on the tip. If the egg has not been fecundated the inside will be uniform, without any blood
vessels and the yolk will be in the middle. In that case scrap the egg. It is likely that in this stage the inside of eggs with a thick
or brown shell cannot be seen well: these will be checked in the second inspection.
2nd Inspection: development of the embryo: The mesh of blood vessels is normally visible in the tip of the egg and
the embryo will appear as a dark spot. If the blood vessels are not visible this means that the embryo is dead.
3rd Inspection: embryo check: The embryo normally occupies the entire egg, therefore the blood vessels should no longer
be visible. The air cell is large, If the embryo does not occupy the entire space, blood vessels are visible, the air cell is small
and the white has not been used up, this means that the embryo is underdeveloped and the egg must be scrapped.
