9 Egg Setting
9.1
The Octagon 20 Advance and Octagon 40 Advance incubators are designed to be as flexible as possible,
accommodating eggs of different sizes up to (and including) goose eggs and in different orientations. Some
experimentation may be necessary to maximise capacity.
9.2
Before setting eggs ensure that the incubator has been run for several hours and has stabilised at the correct
temperature.
9.3
Set the eggs in rows between the wire loop dividers. The dividers must be positioned such that the eggs rest on
the tray bottom and are not pressured by the bar. The dividers prevent the eggs rolling. Eggs may be set on end
(or at an angle) provided the large end of the egg is upwards. Eggs rolling through a few degrees between the
dividers as the incubator turns are not in danger.
9.4
Once the eggs have been set the temperature must not be adjusted for 24 hours to allow the eggs to warm. Check
the water level every 3 days or so and temperature daily. Candle the eggs after 1/3rd of the incubation period has
elapsed to reject clear, infertile eggs (see section 12).
10 Egg Turning
Warning: NEVER MANUALLY TURN THE INCUBATOR WHILE IT IS ON THE CRADLE, this will damage the
turning mechanism and invalidate the guarantee.
10.1
The Autoturn cradle will continuously turn the incubator and eggs on an hourly cycle (through 90° and back)
while plugged into the mains supply. Some small intermittent movement due to play in the gears is normal and
does not cause harm. Lubrication of the plastic linkage with WD40 helps to ensure smooth, silent movement.
10.2
Ensure that nothing can impede the movement of the incubator on the cradle (such as a mains cable or having
the incubator too close to a wall).
10.3
Altricial species such as parrots or birds of prey may benefit from additional manual turning through a full 180°
once or twice a day.
