2. Artificial Incubation

 This is a method where an incubator machine is used to hatch

the eggs.

 Some incubators use a lamp to supply heat while others use

electricity

 After incubation, chicks

are separated according

to their sexes (chick sex-

ing)

Advantages of artificial in-

cubation

 Very many eggs are

hatched at the same time

 Because of effective control, a big percentage of fertilized eggs

hatch successfully.

 Because of the above reasons it is ideal for commercial use.

Disadvantages of natural incubation

 It is an expensive method to setup and manage

 It needs special attention and care

 There must be someone to always supervise it.

 In case of mistakes in management, the losses can be very se-

vere.

 It requires constant power or a heat supply.
