fall. There is no need to worry- because the incubator was open a lot of warmth has
escaped and the temperature of the eggs is much lower. It would be wrong to turn up
the heating as the eggs first have to adopt the breeding temperature. After a few hours
the thermometer will show the correct temperature. Sometimes a little adjusting may be
necessary but it should be taken into account, not to turn the thermo control unneces-
sarily – especially after opening the incubator.
The eggs trays with rollers are adjustable to each size of egg by fitting the gaps between
the rollers to the egg size, that is to say the egg lies horizontally on two rollers. The eggs’
blunt ends should lie opposite other blunt ends and the pointed eggs towards each
other so the eggs do not pile up.
Incubating temperature
The ideal temperature recommended by experts is 37,5 °C in the beginning. A proven
fact is, that the temperature to strive for is 37,8 °C / 100 °F. For the three days before
hatching the temperature can be about 0,5 °C to 1 °C less.
The hatch
If the incubating has gone well, you can be relaxed while you await the day of hatching.
You should then move the eggs to the Hatcher, or, if you plan to do the hatching in the
same incubator, suit the temperature and the humidity to the eggs. Take out the trays
with rollers and put the eggs on the grating floor. It is often more favorable to put the
eggs in special hatching trays.
To avoid bad pollution during hatching you could cover the floor of the incubator with
paper before. The temperature for the hatch should be around 37° C. To raise the
intake of oxygen for the chicks, experts recommend to put some kinds of eggs into a
leach with diluted hydrochloric acid. This will remove the layer of fat. (5 liters of water, 1
tablespoon of 18 per cent hydrochloric acid). The temperature in the leach should be
about 37 °C, after the bath the eggs should be cleaned thoroughly with fresh water (also
37 °C warm). For other eggs it is sufficient to brush of the layer of fat carefully to enable
a better way through for the oxygen.
To supply the eggs with the necessary humidity during the hatch, first of all the openings
for the fresh air should stay closed. By adjusting the openings, you can dispense the
humidity in the incubator.
Please do not open the incubator unnecessarily until the last chick has freed itself from
its shell.
