Important note on the parameters: Regarding the term 'internal temperature' ("internal"), do not con-
fuse the term 'internal temperature' (inside the egg) with 'internal temperature incubator'. The internal
temperature within the incubator constantly changes up and down. The internal egg temperature thus
is the average of the temperature fluctuations inside 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. The required temperature depends on the type of incubator, too.
Example based on a chicken egg:
With surface incubators (breeding on an even surface), the breeding temperature is measured on the
height of the egg's upper edge and should be between 38.0°C and 38.3°C. If a motorised incubator
(breeding process on multiple stories on top of/next to one another) is used, the measured temperat -
ure should be at around 37.5°C at any point of the egg.

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 ones. 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 be difficult, even with good ther-
mometers. If you run 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, 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 inside the incubator in order to be able to per-
ceive the various temperature differences and readjust the incubator temperatures correctly.
