Manual

Hatching

23. Stop egg turning 2 or 3 days before hatch is due. Remove the rods.

24 hen first egg pips, raise humidity to maximum by adding warm

water to both pans.

(Hatchmaster A: move ventilation lever to right).

25. Keep the incubator lid on and don’t interfere! Humidity will rise

rapidly when chicks emerge and condensation may form.

26. When most eggs have hatched (12 to 48 hours) remove

hatchlings to a brooder to dry out. (Brinsea Cosy-Lamp

recommended or TLC-4 Brooder or Parrot Rearing Module

for exotics).

Cleaning up

27. Unplug from the electrical supply!

28. Discard shells and unhatched eggs. Wash the egg tray in

running water. Wipe incubator base with a damp cloth and

dry thoroughly.

29. Remove dust from incubator top with a soft brush.

Caution: Keep electrical parts dry!

Servicing

30. No routine servicing is necessary other than cleaning. In case of

failure refer to your distributor or to Brinsea Service Department.

All operational parts are available and may be fitted by a suitably

qualified person. Instruction sheets are supplied with replacement parts.

7 Temperature variations (day to night for example) or constantly

low temperature can cause malformations or partial development

of the embryo. Constantly high temperature will tend to speed up

development but risk early death from heat stress.

Brief temperature reduction when checking water levels or

inspection will not affect the development of embryos.

Humidity and Ventilation

Note: Short term variations in humidity are not

important.

The average

over the incubation period needs to be near

optimum for the ideal weight loss.

8. Recommended humidity:

During incubation: Poultry 40-50% RH

Waterfowl 50% RH

Exotics Check literature

As a general guide for poultry, set the eggs with water in just one

pan (Hatchmaker-inner ring) and adjust humidity according to

weight loss or air space development.

If the incubator is less than half full, cover two ventilation holes

in the lid to reduce ventilation. At hatching stage, humidity will

rise sharply as chicks emerge.

9. To increase

humidity, increase wet surface in incubator by filling

both water pans in the moulded base.

10. To reduce

humidity, reduce wet surface and if necessary increase

ventilation. (Hatchmaster A: move damper lever to the left).

11. Caution: excessive humidity can cause problems!

The air pocket in the egg should occupy between a quarter and a

third of the egg at time of hatching. If humidity is too high,

chicks will be wet and sticky and the air pocket too small leading

to death 24 to 48 hours before hatching.
