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 inside the incu-
bator.
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 incubators (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. Your incubator is a surface incuba-
tor.
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). 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 during 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 an example:
