9.1 

The Octagon 20 Advance is 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).
