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 multiple 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 changes of temperatures. Additionally, the incubator should be kept with the included
Styrofoam packaging, this provides protection.
1. How have the eggs to be stored before placing them into the incubator?
Hatching eggs should not be kept longer than ten to twelve days. After that the success rate of hatch-
ing is very low. Store the eggs at a cool temperature (8–15 ℃) and at a relative air humidity of 75 %. In
case the hatching eggs were sent via post, they should rest for at least 24 hours 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 it is possible, let
the incubator run for a week without eggs. This way it is easy to see if all parameters can be adjusted
and working as required. Additionally, you will learn how the functions and the adjustments of the in-
cubator work during this time. Nothing is more harmful to the eggs than the wrong adjustments of the
incubator. If everything worked accordingly in the testing period, the incubator can be cleaned thor-
oughly 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.
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-

http://www.WilTec.de
http://www.aoyue.eu 05 2021-1
http://www.teichtip.de
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. What has to be the air humidity rate?
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:
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 the egg. Without the increased humidity, the chicks cannot break through the mem-
brane and therefore also not 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.

http://www.aoyue.eu 05 2021-1
http://www.teichtip.de
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 breeding time?
Poultry type
Breeding time [normal deviation: 1–2 days]
Chicken
20–21 days
Duck
28 days
Pigeon
18 days
Goose
30 days
Quail
16–18 days
7. When start to turn and at what frequency? When are they not allowed to be turned any long-
er?
Your incubator is equipped with a fully automatic turning system. The automatic turning system
of the appliance turns the eggs slowly and consistently. Therefore, the eggs can be turned from day
one. The system is so slow that the embryos are not exposed to shocks. This is because they are very
sensitive and sudden movements should be avoided, especially in the first few days. If possible, the
incubator should remain closed for the first three days to create an ideal 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. The humid, warm atmosphere needs to stay con-
sistent during the last days of the breeding, to soften the egg membrane and enables the hatching
process.
Note: Most chicks do not cope with a complete collapse of the climate.
9. 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
1. The package contains an incubator for
24 eggs, an operating manual, styrofoam, a pow-
er supply unit and a water container.
2. Power supply connection.
3. Make sure that the egg insert slot of the motor
shaft connection on fits on both sides.
4. Ensure that the insert fits the outer casing.

http://www.teichtip.de
5. Ensure, that the ventilation, temperature dis-
play, operating buttons and heater work properly.
Attention: Place the incubator into the Styrofoam
to keep the temperature constant if it drops below
20 ℃.
6. Fill water into the incubator for preheating and
start the test run.
Breeding notes: The first step to successful hatching is the selection of the best fertilised eggs. But
how are these selected?
1. The fertilized eggs need to be fresh and within the time frame of 4–7 days after being laid. The best
temperature to store the fertilised eggs is 8–15 ℃. The fertilised egg is covered with a powder like
substance, which must not be wiped off or stored in the fridge.
2. The surface of the eggshell needs to be free of any deformation, tears or marks.
3. There is no necessity to disinfect the fertilised eggs, as an improper disinfection can negatively im-
pact the hatching rate. Just ensure that the eggshell is clean and without marks.
4. When placing the egg into the incubator, ensure that the tip of the egg points downward.
5. A proper operation and supervision are required during the breeding process. Amongst other things,
this means adding water regularly, every 1–2 days (dependent of the surrounding, the water level and
the air humidity in the incubator).
6. The fertilised eggs cannot be tested within the first four days of the breeding, as a decrease of tem-
perature in the incubator has a negative impact on the early development stages of the egg.

http://www.teichtip.de
7. The first testing of the eggs (after 5–6 days): Mainly for checking the fertilisation of the eggs. Re-
move the unfertilised, yellow and dead eggs.
The second testing of the eggs (after 11–12 days): Mainly for checking the development of the em-
bryo. A well-developed embryo is bigger and has blood vessels inside it. The air cell should be big and
sectioned off noticeably.
The third test of the eggs (after 16–17 days): Illuminate the egg from the side. A well-developed em-
bryo is bigger and should fill the egg out nearly entirely, letting hardly any light through. If the embryo
is dead, the blood vessels in the egg blurred, parts near the air cell are discoloured yellow and the
sections between the egg and the air cell is not clearly defined.
8. Increase the air humidity during the breeding time and decrease the temperature. This disables the
water in the eggs from evaporating too fast. The most important factor is the air humidity though,
avoiding dehydration and the temperature decrease to avoid too high temperatures and too high hu-
midity. Especially if the hatching time is spreading out over a longer time. The temperature should not
be more than 37.5 ℃in 19–21 days.

2. Connect the electricity supply cable included in the delivery to the electricity source.
3. Switch the electricity source on.
4. Switch the incubator on.
5. An alarm will sound, due to low temperature/ humidity. This is normal.
6. Press a random button to turn the alarm off.
7. Let the incubator run and fill the water channels. You will notice that the humidity will increase.
8. Push the reset button, to check the automatic turning mechanism. This will begin every two
hours and takes 10 s.
Adjusting the Temperature
1. Push the settings button.
2. Push the “+” or “–” button, to adjust the desired temperature.
3. Push the settings button again to end the adjustments.
The incubator is pre-set to 38 ℃. If the chicks already hatch on day 19 or 20, this means the tempera-
ture is set too high. Use the process as described above. A temperature adjustment of 37.6 ℃is rec-
ommended.

Adjusting the temperature parameters for the temperature alarm (AL and AH)
The temperature alarm is pre-set to sound, as soon as a temperature of 1 ℃or less is reached.
Setting the low temperature alarm (AL)
1. Push and hold the settings button for 3 seconds.
2. Push the “+” or “–” button until “AL” is shown on the temperature display.
3. Push the settings button.
4. Push “+” or “–” to set the alarm as required.
Setting the high temperature alarm (AH)
1. Push and hold the settings button for 3 seconds.
2. Push the “+” or “–” button until “AH” is shown on the temperature display.
3. Push the settings button.
4. Push “+” or “–” to set the alarm as required.
Adjusting the parameters for the air humidity alarm (AS)
The temperature alarm is pre-set to sound, as soon as a temperature of 45 % is reached. This is suffi-
cient and does not need to be altered.
Setting the low humidity alarm (AS)
1. Push and hold the settings button for 3 seconds.
2. Push the “+” or “–” button until “AS” is shown on the temperature display.
3. Push the settings button.
4. Push “+” or “–” to set the alarm as required.
By filling water into both water channels, the air humidity should rise by 60 %, depending on the local
humidity and season of year. It is recommended to fill the water channels up every 4–5 days. On day
18, when the egg inserts are removed, they should be overfilled, to raise the humidity to approx. 65 %.
Make sure that neither the eggs, nor the equipment are allowed to get wet.
Calibration of the temperature measurement (CS)
The correct measured value of the thermometer is set to 0 ℃. The displayed value of the thermometer
can be adjusted if you realise that the temperature value is wrong with a calibrated thermometer.
Calibration of the temperature sensor measurement
1. Push and hold the settings button for three seconds
2. Push the “+” or “–” buttons, until “AH” is displayed on the temperature display.
3. Push the settings button.
4. Push “+” or “–” to set the alarm as required.
Make sure that the adjustments are the deviation between the thermometer values and should be
adjusted with the “–” if the temperature of the incubator is too high and the normal value (display +
value) is too low.
Adjusting the upper and lower temperature limits (HS and LS)
HS (high setting) and LS (low setting) adjust the limits of the adjustment range of the desired tempera-
ture (incubation temperature regulation).
If HS is set to 38.2 ℃and LS to 37.4 ℃, the desired temperature (adjustment of the incubation tem-
perature) can only be altered from 38.2 ℃to 37.4 ℃, thus the minimum temperature is limited to
37.2 ℃, even if the “–” button is pushed down and held. The same applies to the high setting. This
disables an accidental change of temperature outside of the required range.

Notes on the first breeding with the incubator
1. Test the incubator for its functionality.
2. Connect the plug of the incubator with the control plug of the egg insert.
3. Fill water into one or both water channels, depending on the local air humidity.
4. Lay the eggs with the tips of the egg pointing downward.
5. Close the lid and switch the incubator on.
6. Push the reset button (left green button), to reset the day count to 0 and to start it (this will al-
so reset the egg turning countdown to 1:59 h).
7. Pay attention to the humidity measurements and refill water when required (usually every
4 days).
8. On day 18 the egg insert should be removed and the eggs should be placed onto the wire.
9. At the same time it is important to fill the water channels up, to increase the humidity. (This is
very important, to ensure the eggshells are soft enough for the chicks to break through).
10. Do not open the lid regularly when the chicks begin to hatch. If this is done, the humidity is lost
and the eggshells of the chicks still needing to hatch will dry out. The chicks cannot break
through the eggshell.
