Of the two methods given above the most reliable is egg weight method and is recommended –
particularly where poor hatch rates are experienced or if eggs of high value are being incubated.

Alter the setting of the ventilation control (reduce ventilation to increase humidity) and have water in
neither, one or both of the water channels to change the humidity level. Humidity levels may be further
increased by placing strips of evaporating card or cloth into one or both of the water troughs. Evaporating
card is available from Brinsea Products.

In all cases the humidity for hatching needs to be high. Because of the short duration involved
water/weight loss will not be significantly affected. High humidity is necessary to prevent membranes
drying and hardening before the hatch fully emerges. Humidity will naturally increase as the first eggs
begin to hatch and internal membranes begin to dry. This effect is in addition to the increased area of
water evaporation from the water channels.

During hatching the high humidity levels will fall dramatically when the lid is opened and will take some
time to build up. Resist the temptation to lift the lid frequently – leave for at least 6 hours between
inspections.

The Brinsea Advance Humidity Pump is available as an option on the Octagon 20 Advance incubator.
The incubator digital control system not only reads the humidity in the incubator but it provides a control
signal to operate the water pump and accurately maintain the humidity level at the desired level.
