The right location
For a good result, place the incubator into a heated room. There should not be any major fluctuations
of room temperature inside it. Ideally, the room temperature should be comprised between 17 ℃ and
25 ℃.
Additionally, there should be a good ventilation in this area. Especially with presence of several incuba-
tors, you should make sure sufficient ventilation. A natural air supply ensures that the developing em-
bryos always have fresh oxygen.
Make sure that the incubator is placed on a flat, even surface and not in direct sunlight. Place it on a
solid surface which is approx. 80 cm above the floor.
It is recommended to place the incubator far away from heating sources, drafts, and windows to avoid
harmful temperatures fluctuations. Additionally, the incubator should be kept with the included polysty-
rene packaging, which provides protection.
General information on breeding
1. How do the poultry eggs must be stored before placing them into the incubator?
Hatching eggs should not be kept longer than ten to twelve days. After that, the hatching success rate
is very low. Store the eggs at a cool temperature (8–15 ℃) and at a relative air humidity of 75 %. If the
hatching eggs have been sent you via post, they should rest for at least 24 h before being placed in the
incubator.
Important: The eggs should be stored lying and need to be rotated halfway around their longitudinal
axis at least once a day.
2. When is the incubator ready?
The incubator should run for at least 24 hours before placing any eggs into it. If possible, let the
incubator run for a week without eggs. Thus, you will easily see if all parameters can be adjusted and
work as required. Additionally, you will learn how the incubator functions and adjustments work during
this time. There is nothing more harmful to the eggs than wrong adjustments of the incubator. If every-
thing works accordingly in the testing period, the incubator must be cleaned thoroughly with a suitable
disinfectant.
The intended humid and warm climate in the incubator is a good breeding ground for bacteria and fungi.
Not disinfecting the incubator invites the growth of these, posing a threat to the entire brood. Thus:
Before the first breeding and after every new breeding, thoroughly disinfect the incubator.

http://www.WilTec.de
http://www.aoyue.eu 03 2022-1
http://www.teichtip.de
You need to make sure that the disinfectant is suitable for the material of the incubator. Otherwise, the
material can be attacked and the hatching process endangered.
Important note on parameters: Be sure to properly understand the term “internal temperature” (“inter-
nal”). Do not confuse the term “internal temperature (inside egg)” with “internal temperature (inside in-
cubator).” The internal temperature within the incubator constantly changes up and down. The internal
temperature of the egg thus is the average temperature of the temperature fluctuations in the incubator.
3. Which temperature should my incubator have?
The required temperature depends on the individual type of animal. For every type of animal has its own
requirements and even amongst poultry there are differences regarding the temperature required during
the breeding process. The required temperature depends as well on the type of incubator.
An example based on a chicken egg:
With so-called surface incubator (breeding on an even surface), the breeding temperature is measured
on the height of the upper edge of the egg and should be between 38.0 ℃ and 38.3 ℃. If a so-called
motorised incubator (breeding process on several levels one above the other) is used, the measured
temperature should be at around 37.5 ℃ at any point of the egg.
An overview of various poultry types and the breeding temperatures required:
Type of poultry
Breeding temperature (℃)
Chicken
37.4–37.6
Duck
37.4–37.6
Pigeon
38.5
Goose
37.6
Quail
37.6–37.8
Note: A short temperature drop while checking the eggs usually is not a problem for the embryos. Con-
trariwise, temperatures exceeding the recommended one are harmful and even deadly and should be
avoided at all costs.
4. Does my thermometer show exact values?
Thermometers are not exact. Keeping the temperature constant might be difficult, even with good ther-
mometers. If running a big incubator over a longer period of time, you can optimise the temperature,
regardless of what the thermometer states.
After the first breeding process, you may modify the temperature (set it to a higher or lower value).
With poultry: If the hatching takes places in an early stage, the temperature should be lowered. If the
hatching is delayed, it needs to be increased.
How to check the thermometer: Keep notes regarding the time of the brood, as these are a reliant
aid. You will soon have the required routine to select the right adjustments and settings for a successful
hatch.
Alternatively, an additional thermometer can be placed in the incubator to be able to see the various
temperature differences and readjusting the temperatures of the incubator accordingly.
5. How high must the air humidity be?
The air humidity required varies again depending on the brooded type of animal and needs to be
changed during the breeding process.
Inform yourself beforehand on the requirements to be met in the incubator. To give you two examples:

© by WilTec Wildanger Technik GmbH Item 51185, 51186 Page 6
http://www.WilTec.de
http://www.aoyue.eu 03 2022-1
http://www.teichtip.de
Chicken eggs:
Day 1–18: 50–55 % air humidity
From day 19: 70–75 % air humidity
Quail eggs:
Day 1–14: 55 % air humidity
From day 15: 75 % air humidity
The air humidity is increased towards the end of the breeding with poultry eggs to soften the hard egg
membrane. Without increased humidity, the chicks can neither break through the membrane nor through
the egg shell. Yet, the humidity should not be increased too much, as the chicks might drown.
Note: The humidity is checked with a so-called hygrometer. It is near enough impossible to keep hu-
midity as exact as temperature, especially in small incubators. Just try to keep it as exact as possible.
The temperature is the significant criteria. Even a small deviation (even a couple of degrees) can ruin
the breeding process or lead to a bad result.
Important: The air humidity changes just like the season.
If the breeding is carried out in January and February, it is very difficult to keep the humidity at the
desired level, as the external humidity is rather low (depending on the location).
In June and July, the external humidity usually is higher, resulting in the humidity in the incubator being
higher than desired. To avoid these problems, change the water surface in the incubator: To increase
the humidity and thus to enlarge the water surface, place an additional container with water/a few small
moist sponges in the incubator. Alternatively, the eggs can be sprayed with fine water mist. To reduce
the humidity, decrease the water surface by using smaller containers.
Important: Choose the shape and execution of the water containers keeping in mind, that they should
not become a fatal danger for the hatched chicks and reptiles.
6. How long is the incubation time?
Poultry type
Incubation time (days) [normal deviation: 1–2 days]
Chicken
20–21
Duck
28
Pigeon
18
Goose
30
Quail
16–18
7. Poultry eggs: When start to turn and how frequently? When do the eggs not must be turned
any longer?
The incubator does not have an automatic turning mechanism; thus, the eggs need to be turned
by hand. The embryos are very sensitive in the first days, therefore shakes should be avoided. This
also means that the eggs should only be turned from the fourth day onward. The easiest method of
assistance is to carefully mark the egg on two opposite areas, to see to which area the egg needs to be
turned to. It is recommended to turn the eggs 5 times a day with a minimum of 90°.
Additionally, the incubator should be kept closed within the first three days of breeding, if possible. This
allows for a better climate to build up.
Important: In the last two to three days of the breeding process the eggs must not be turned any
longer. For the chicks are finding a hatching position, which must not be changed any more.

8. What is to regard with the last days of the breeding process?
In the last two to three days before hatching, the poultry eggs must not only not be turned anymore, but
also does the entire incubator need to stay closed. For the humid-warm atmosphere needs to be pre-
served during the last days of the breeding to soften the egg membrane and enable the hatching pro-
cess.
Now you can choose if you wish to switch off the turning mechanism via the functional menu (therefore,
set the turning interval/turning duration to “0”) or to remove the whole turning insert. In case you remove
the turning insert, carefully open the device and take out the egg. Then place them on the bottom of the
device. Try to keep opening of the device as short as possible, then spray the eggs with warm (not
boiling!) water from a spray bottle. Thus, in most cases, the damp-warm climate inside the device will
be preserved.
Note: Most chicks are not able to cope with a complete collapse of the climate.
9. Poultry eggs: What happens after hatching?
Congratulations, your chicks have hatched! Have a little patience, as the freshly hatched chicks should
stay in the incubator for approx. 24 hours longer to be able to recover and dry off.
Important: Remove the water container. Otherwise, the humidity is too high for the chicks, and there is
the danger of the chicks drowning. However, you must develop a sure instinct for possible Johnnies-
come-lately still need humidity to hatch.
If these latecomers, pecking the egg from the inside, have difficulties getting through the eggshell, you
can provide a starting aid by carefully opening the eggshell a little bit. Certainly, a sure instinct is needed
as well in this condition for you must not help them too early. Oftentimes, a wrong humidity can be the
reason for that, as the egg membrane can dry and get stuck to the chick before it is able to get out.
Thus, the chick cannot turn any longer and hatch.
Note: There must be a sufficient fresh air flow, too, as the young animals can otherwise suffocate in the
closed container. If an integrated air hole is available, it will ensure for fresh air.
Operation
Before the eggs are placed in the incubator, regard the following:
•Open the packaging and check the content on integrity.
Note: The incubator should stay in the styrofoam packaging. This, on the one side helps save
energy, on the other side the eggs are protected from external influences. If there are no holes
for the according connections and switchboards, these need to be added. Carefully use a sharp
knife or small saw.
•Open the lid of the incubator and remove all included parts, except for the turning mechanism.
•In the lid of your incubator, you will find a connection point for the cable of the turning mecha-
nism, besides the thermometer and the humidity sensor. Place the cable of the turning motor of
the lower bit into this connection point, so that the turning mechanism is connected to the elec-
tricity circuit.
•If all cables are connected properly, check the compliance of the operating current as stated on
the device with the used mains voltage. If it matches, the device can be closed via the lid and
the electricity can be switched on. The device will start heating to the temperature, which is
analogously shown on the system’s switchboard.
•Leave the incubators run for at least 24 hours without any eggs inside and get accustomed to
the functions of the incubator. Make sure that all parameters can be adjusted without a problem
and how to change settings, such as the temperature alarm (regarding the paragraph “Display,
function buttons and basic settings”).

http://www.teichtip.de
•Check the individual values with the help of an additional thermometer and hygrometer. If nec-
essary, calibrate the values. Test how you can keep the desired air humidity at the right level/
how much water is required to stay in the desired range.
•If the incubator works without a problem, and you are accustomed with the functions, unplug
the incubator and clean it from the inside and the outside with a suitable disinfectant.
Adding the eggs
•As soon as the incubator has been cleaned, you can place water into the grooves. Please note,
that the air humidity should be noticeably lower at the beginning of the breeding process than
towards the end (at least for most bird types). Therefore, only fill a little bit of water into the
grooves at the beginning. The incubator has a small opening on the side (see picture 3), through
which water can be filled when needed (too low air humidity). Thus, the lid does not must be
opened during the breeding process.
Note: Please note the individual requirements of every type of animal. Do not place too much
water into the incubator as this can lead to bad hatching results. Ideally, you have already found
out how much water is required at the beginning.
Note: If the humidity is too low, even though the two grooves are filed with plenty of water, a
bowl can be added to the incubator. Please be careful not to make the eggs or the inlay wet.
Do not keep the incubator open for too long, when placing the bowl, as this can have a negative
impact on the hatching result.
Important: Choose the shape and design of the water bowls, making sure they do not pose a
fatal risk to hatched chicks and reptiles.
After adjusting the according parameters of the incubator, the eggs can be placed into the incu-
bator with the tip downward. Set the number of days to 0.
•Regularly check the temperature and humidity on the
control panel of the incubator and, if necessary, alter the
parameters. Pay attention to the water level in the
grooves of the incubator, there should always be enough
water.
Important: There must be no water on the egg inlay! This
can otherwise have a negative impact on the hatching re-
sults!
•Towards the end of the hatching process, the poultry
eggs must not be turned any longer. The automatic turn-
ing mechanism needs to be switched off then. Therefore,
the electricity supply neds to be disconnected between
the turning motor and the turning insert, by disconnecting
the cables. The according cables can be found in the turn-
ing insert.
Fig. 3: Opening for water refill
•It is also possible to remove the turning mechanism entirely. Open the incubator, disconnect
both cables of the turning motor from one another and lift the turning mechanism out of the
incubator. Then place all eggs carefully back onto the insert in the incubator. Spray the eggs
with warm water and carefully, yet fast place the eggs, allowing for the humid and warm climate
to be kept sustained.
Important: Please note that the incubator should not be opened towards the end of the breeding
process with more sensitive species. Thus, ensure that the humidity is high enough, as soon as
the eggs are placed still and the turning mechanism is switched off. During the hatching process,
the lid should remain closed. Water can be refilled via the hole, to avoid the eggshells from
drying out.
•During the hatching process, the lid should remain closed. Water can be refilled to protect the
eggshells from drying out.
•If the chicks have hatched, you need to ensure they cannot drown, whereas chicks still breeding
need to hatch.
