Humidity Adjustment
Humidity adjustment in incubators is for
providing adequate water loss from eggs
. And also
high humidity levels for last 2-3 day
are
also very important.
Egg needed to lose between 13-16 % water depending on the species during incubation period. Weighing of eggs
during incubation is most trustable method to find proper humidity needed to good hatching results for particular poultry species.
Different from temperature, short term humidity changes during incubation are not important. Providing an average humidity in desired level
during all incubation period is enough to achieve good results. However, high humidity levels during hatching period ( last 2-3 day) is very
important. When the chick started to hatch, inner membrane of egg dries quickly. This makes membranes harden and chick can stick to
shell. To prevent drying of membranes, humidity must be adjusted to high levels depending on species for last 2-3 day of incubation.
Cabinet humidity value can be adjusted by water channels. Humidity values are shown in control panel digitally.
Humidity levels directly result of
water surface area in base.
PD models have different size of water channels to adjust humidity at desired
level.
Lowest humidity
Highest humidity
Don’t forget that humidity values depend on temperature values, always check humidity values at temperature set point.
You could not decrease humidity below a point and could not increase above a point . This low and up limits depend on humidity level of
your incubation room.
CAUTION!
Never fill humidity trays with cold water. Use warm water close to incubator temperature set point. Ideally 25-35
