The right location
For a good result, place the incubator in 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 good ventilation in this area. Especially with the presence of several incubators, you should make sure sufficient ventilation. 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. 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 temperature fluctuations. Additionally, the incubator should be kept with the included polystyrene packaging, which provides protection.

General information on breeding

  1. How must the poultry eggs be stored before placing them in 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 to 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 everything 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. 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” (“internal”). Do not confuse the term “internal temperature (inside egg)” with “internal temperature (inside 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. 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.

  4. An example based on a chicken egg:
    With a 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 motorized 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. Contrariwise, temperatures exceeding the recommended one are harmful and even deadly and should be avoided at all costs.

Does my thermometer show exact values?
Thermometers are not exact. Keeping the temperature constant might be difficult, even with good thermometers. If running a big incubator over a longer period of time, you can optimize 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 readjust the temperatures of the incubator accordingly.

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:

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 eggshell. 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 humidity as exact as temperature, especially in small incubators. Just try to keep it as exact as possible.
The temperature is the significant criterion. 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 enlarge the water surface, place an additional container with water 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.

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

Poultry eggs: When start to turn and how frequently? When must the eggs not 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 anymore.

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 preserved 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.

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 to 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 mechanism, 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 electrical 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 running 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”).

  • 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 to 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 must not 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 filled 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 to parameters of the incubator, the eggs can be placed into the incubator 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 results!

  • Towards the end of the hatching process, the poultry eggs must not be turned any longer. The automatic turning mechanism needs to be switched off then. Therefore, the electricity supply needs 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.

  • 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.

Description of the function buttons

The incubator has four buttons, which are required for the operation of the incubator. The buttons and their possible combinations will be explained in the following paragraph. Before operating the incubator, ensure that it is properly plugged into the according area.
The buttons are positioned the following from bottom to top, next to the display on the right-hand side: “set,” “+” and “–.” On the left-hand side of the display, there is the “reset” button.

  1. Press “reset” briefly: This button allows to turn the eggs manually.
    • Pushing the button once shortly will turn the eggs. The symbol 1 will blink in the display.
    • The countdown for the automatic turning is then reset to 2 h again.
  2. “Set”: This allows to set the basic temperature of the incubator.
    • Pushing the button once shortly will allow you to set the basic temperature (parameter ID: PP).
    • By activating the “+” and “–” buttons, the desired temperature can be adjusted, by push-ing the “set” button again the data will be saved.
    • The pre-set temperature is 38.5 ℃, the basic temperature can be chosen between 30 ℃ and 39.5 ℃.
  3. Holding “set” for longer than 3 s: This will open the menu for the finer parameter settings (see table 1).
    • The individual parameter will show in the display, with an alphanumerical combination (parameter ID).
    • With the “+” and “–” buttons you can choose between the individual parameters.
    • If you wish to adjust one of the parameters, push the “set” button then alter the shown value up or downward by pushing the “+” or “–” button.
    • Pushing “set” again, will save the alteration and will bring you back to the standard display.

Finer parameters| Parameter ID| Adjustment range| Standard-setting| Note
---|---|---|---|---
Alarm, fluctuation of decreasing temperature| AL| 0–15 ℃| 1.0 ℃| This setting can be chosen, to sound an alarm when a temperature below the setting is being reached. After setting the parameter “PP” to the value, e.g., to 38 ℃, and you wish to have the alarm set for 33 ℃, you will

need to set the parameter “AL” to 5.

Alarm, fluctuation of increasing temperature| AH| 0–15 ℃| 1.0 ℃| This setting can be chosen, to sound an alarm when a temperature above the setting is being reached. After setting the parameter “PP” to the value, e.g., to 38 ℃, and you wish to have the alarm set for 40 ℃, you will

need to set the parameter “AH” to 2.

Alarm,    fluctua- tion of humidity| AS| 1–99 %| 45 %| Here you can adjust when the alarm is to sound in case of a fluctuation in humidity. By setting the required hu- midity, the alarm will sound if the hu- midity measures deviate from the setting. Important: The humidity needs to be regulated manually by adding water to the incubator. The alarm will only notify you, that the

humidity is too low/ high. The setting

        needs to be adjusted manually for each breeding phase.
Calibration CA 0–9.9 0.0 Measure with an additional thermometer and match

it according to the deviation.
Heating start| LS| 20–30 ℃| 30 ℃|
Heating stop| HS| 30–50 ℃| 39.5 ℃| Please note that the radiator will switch off when reaching the entered value, but will still radiate some warmth and the temperature might still rise a little bit in the incubator. E.g., this means that a temperature of 38 ℃ can be reached when setting the temperature to 37.8 ℃. If you wish to avoid this, the temperature of the heating stop needs to be corrected downward.

NOTE:
As from version quarter 1/2021, the procedure for resetting the number of breeding days has changed:
Press and hold “Reset” for approx. 3 s, pull out the mains plug and plug it in again. The display shows a countdown to 0. After the countdown has elapsed, the number of breeding days is reset.
