1. Egg and incubator hygiene

Proper hygiene is essential to achieve good hatching results. Poor hygiene causes

chicks to die in their first 10 days of life.

Only clean eggs should be used for incubation. Dirty eggs are potential carriers

of diseases that thrive and multiply in the ideal heat and moisture conditions of

the incubator. If you need to incubate dirty eggs, wash them first in warm water

(44-49

C) that contains disinfectant at a rate recommended by the manufacturer

(most household disinfectants are suitable), and dry the eggs quickly after

washing using separate paper towels.

Do not soak eggs for longer than four minutes to avoid affecting fertility and do

not soak eggs in cold water, as it encourages bacterial penetration through the

eggshell.

Fumigating eggs immediately after collection also helps with hygiene. A suitable

fumigant is formaldehyde gas, which is made by mixing 1 part (by weight) of

potassium permanganate (Condy's crystals) with 1.5 parts (by volume) of

formalin (see Table 1 for the correct amounts for each application). Place the

chemicals in a dish on the floor of the incubator. Place the Condy's crystals into

the dish first and then pour the formalin over it. Shut the incubator door quickly

and vacate the room.

For proper fumigation, run the machine normally with the correct temperature

and humidity. After 20 minutes, open the vents or the door and air the machine

for a few minutes. Again, vacate the room.

2. Healthy stock

It is important that eggs from only a healthy flock are used for hatching, as some

diseases can be transmitted through the egg. The egg-transmittable diseases to

be most aware of are salmonella infections, fowl typhoid and Mycoplasma

gallisepticum.

Eggs laid by birds infected with disease may fail to hatch. Of those that do hatch,

some birds may die during brooding, and the survivors may act as carriers and

infect healthy chicks.

Do not add eggs from unknown sources to make up numbers, as you risk

infecting your flock.
