Automatic egg turning
Eggs
must be turned periodically during incubation
to prevent the internal structures from sticking
and to promote embryo development.
The Polyhatch and Hatchmaster 'A' turn the eggs
completely automatically and safely on an hourly
cycle. Brinsea's patented system ensures safe
and reliable rotation of almost any sized eggs
without the need to purchase accessories*. If
hatching in a Polyhatch or Hatchmaster 'A' the
turning system can be disconnected and with the
end covers (supplied) in place and the dividing
rods removed, there is no opportunity for the
chicks to injure themselves on the turning mechanism.
*Note: For quail or other very
small eggs, special egg troughs are recommended.
These are not supplied as standard but are usually
available from stock.
Hatchmaker and Hatchmaster
'H' - Incubators or Hatchers
Whilst
either the Hatchmaker and Hatchmaster 'H' can
be used effectively to incubate from day one through
to hatching, the lack of automatic egg turning
makes these models suitable for reptiles or as
hatchers when used in conjunction with an automatic
setter.
Brinsea
recommend hatching in a separate machine for
the following reasons:
- Automatic
egg turning of later batches of eggs can be
continued without fear of damage to
emerging chicks.
- Contamination
of the automatic incubator is virtually eliminated
so no pauses are required for cleaning. This
enables one batch of eggs to follow another
without interruption.
- The
higher humidity conditions required for hatching
can be maintained in the hatcher, thus avoiding
any compromise in the conditions required for
eggs at earlier stages.
12v
Polyhatch and Hatchmaker
12v
incubators have been developed for situations
where mains supplies are unreliable or for transporting
eggs during incubation. The very low power consumption
enables them to be run from ordinary vehicle batteries
for many hours between charges. 12v incubators
must not be connected direct to mains power, but
can be operated from the mains via a 12v transformer/rectifier
capable of an output of 2.5 amps (Hatchmaker)
and 4 amps (Polyhatch). The voltage is not critical
and may be from 11 to 14 volts provided it is
reasonably constant. |
