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 between 17 ℃and 25 ℃.
Additionally, there should be a good ventilation in this area, especially if there are several incubators
located in this room. There has to be an efficient ventilation, as a natural air supply ensures that the
developing embryos always have fresh oxygen.
Make sure that the incubator is placed on a flat, even surface and not in direct sunlight, 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
styrofoam packaging, which provides protection.
General Information on breeding
1. How do the poultry eggs have to 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, it will be easy to 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. Nothing is more harmful to the eggs than the wrong adjustments of the incubator. If
everything works accordingly in the testing period, the incubator can 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 enables the growth of these and poses a threat to the entire
brood. Thus: Before the first breeding and after every new breeding, thoroughly disinfect the
incubator.

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 notice on the parameters: Regard the term “internal temperature” (“internal”). Do not con-
fuse the term “internal temperature” (in the egg) with “internal temperature incubator.” 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. Every type of animal has its own
requirements and also amongst poultry there are difference, regarding the required temperature during
the breeding process. Also, the required temperature depends on the type of incubator.
An example based on a chicken egg:
With 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 motorised incuba-
tor (breeding process on multiple stories on top of/next to one another) is used, the measured temper-
ature should be at around 37.5 ℃at any point of the egg.
An overview of various poultry types and the required breeding temperatures:
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 drop in temperature whilst checking the eggs is usually not a problem for the embryos.
It is different with temperatures exceeding the recommended one. These are harmful and even deadly
and should be avoided at all costs.
4. Does my thermometer show an exact value?
Thermometers are not exact. Keeping the temperature constant can prove to be difficult, even with
good thermometers. If you run a big incubator over a longer period of time, you can optimise the tem-
perature, regardless of what the thermometer states.
After the first breeding process, the temperature can vary (higher or lower).
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 success-
ful hatch.
Alternatively, an additional thermometer can be placed in the incubator to be able to perceive the vari-
ous temperature differences and readjusting the temperatures of the incubator accordingly.
5. How high must the air humidity be?
The required air humidity varies again depending on the brooded type of animal and needs to be
changed during the breeding process.
Please inform yourself beforehand, which requirements need to be met in the incubator. Here are two
examples:

http://www.WilTec.de
http://www.aoyue.eu 09 2021-1
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, it softens the hard
membrane inside of the egg. Without the increased humidity, the chicks cannot break through the
membrane and therefore neither through the egg shell. Yet, the humidity should also not be increased
too much, as the chicks might drown.
Note: The humidity is monitored with a so-called hygrometer. It is near enough impossible to keep the
humidity as exact as the temperature, especially in small incubators. Just try to keep it as exact as
possible.
The temperature is the significant criteria. Even a small deviation (e.g., 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, leading the humidity in the incubator to be
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 in the in-
cubator/a few small moist sponges. Alternatively, the eggs can be sprayed with fine water mist. To
reduce the humidity, decrease the water surface and use 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 they not have to 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 stay closed within the first three days of breeding, if possible. This
allows for a better climate.
Important: In the last two to three days of the breeding process the eggs must not be turned
any longer. As the chicks are finding a hatching position, thus the position 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 the entire incubator needs to stay closed. For the humid, warm atmosphere needs to stay
consistent during the last days of the breeding, to soften the egg membrane and enables the hatching
process.
Now you can choose if you wish to switch off the turning mechanism via the functional menu (there-
fore, 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 maintained.
Note: Most chicks do not 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. Although, the breeding chicks still need the humidity to hatch. This
means having a feeling to choose the best option for both statuses.
If chicks still in the hatching process start pecking the egg from the inside, but have difficulties getting
through the eggshell, you can provide a starting aid by carefully opening the eggshell a little bit. It is
important to be cautious, not to provide this aid too soon. A lot of the times, a wrong humidity can be
reason as the egg membrane can dry and get stuck to the chick, before it is able to get out of the egg.
Thus, the chick cannot turn any longer and hatch out of the egg.
Note: There has to be a sufficient fresh air flow, 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
electricity 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 prob-

lem and how to change settings, such as the temperature alarm (regarding the paragraph
“Display, function buttons and basic settings”).
•Check the individual values with the help of an additional thermometer and hygrometer. If
necessary, 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
have to 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 nega-
tive 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 in-
cubator 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 incuba-
tor, there should always be a sufficient amount of water.
Important: There must be no water on the egg inlay!
This can otherwise have a negative impact on the hatch-
ing results!
•Towards the end of the hatching process, the
poultry eggs must not be turned any longer. The auto-
matic turning 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 turning 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 in-
cubator. 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 cli-
mate to be kept sustained.
Important: Please note that the incubator should not be opened towards the end of the breed-
ing 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 hatch-

ing process, the lid should remain closed. Water can be refilled via the hole, to avoid the egg-
shells 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 breed-
ing need to hatch.
Display, function buttons, and basic settings
On the outer right corner of the incubator is a connection for the electricity supply. It is important to
connect the electricity completely into the connection point, to allow the incubator to function properly.
As soon as the incubator is connected, it can be switched on and off via the button.
On the display there are multiple display areas (2–5) which show information on various parameters.
Additionally there are further symbols (1, 6, 7, 8) on the display which show information on the pro-
cesses in the incubator.
Besides the display and the “on/off” button, there are four more buttons with which the incubator is
operated (see the section “Description of the function buttons”).
The incubator with the item no. 51185 has one more button, “egg candler” (9). This allows to screen
the eggs.
