Humidification; Eggs Candling - Fiem SMART Manual De Uso

If it had not to reach the working temperature above marked, the thermostat will be setted as follows:
• modify the temperature (if necessary) using a screw-driver, turn the screw SET in correspondence of the
requested value 100°F onto thermometer.
IMPORTANT:
if all the attempts of setting instrument result useless, do not remove it from its place absolutely to effect impro-
per and not authorized operations; contact the builder about the possible reparations or substitutions.
In order to guarantee to the eggs a constant and homogenous air flux, it is suggested to interchange the eggs
between themselves weekly.
Remember that two days before period hatcher it needs to disconnect automatic egg-turner kit by the elec-
tric plug.
When the hatching period (last 2 days) is finished, keep the chicks 1 days more in order they dry up and then
put into the electric poultry brooder or under infra-red lamp for almost 3 weeks; maintain a temperature of 35°C
for the first week.
HUMIDITY
It is important to understand that there can be no hard and fast rule for the amount of water required in an
incubator as all the following variables come into play:
- Ambient humidity in the room (affected by the weather and your local environment, eg.on the edge of a lake!)
- The species of the eggs
- The porosity of the eggshells (can vary from egg to egg!)
- The time of year (warm weather usually means high ambient humidity and eggs laid towards the end of the
season tend to be more porous)
Requirement for water in the incubator can be monitored by either weighing the eggs ( or batch of eggs), (an
egg should lose 13-15% of its weight during incubation) or by candling (the air space should be approx. 1/3
of the egg by the time it is due to hatch)

HUMIDIFICATION

For a correct humidification during the incubation time, fill some water (1-2 cm) on the bottom of the incuba-
tor and re-fill water only when the basin is empty.
SPECIE
Hen – Guinea fowl –Turkey-
Pheasant – Red leg - partridge
Quail – Bob white
Goose - Duck
During hatching period, when chicks will start to born, fill hot water into all four spaces on the bottom in order
to increase to the maximum level the humidity inside.
On subsequent hatches you may wish to increase or decrease the amount of water, depending on your fin-
dings with your first hatch, if in doubt, it is better to add too little water than to much - more eggs are lost
through too high humidity than any other single factor! Remember, the depth of water makes no differen-
ce to the humidity levels in the incubator; it is the surface area which counts!

EGGS CANDLING

At 8th - 10th day of incubation, it is advisable to candle the eggs in order to eliminate those which are infertile; this
operation must be done in a dark room. By observing the inside of a developing, fertile egg, using a suitable candling
lamp, it is possible to determine the embryo development which looks like a small reddish shape, composed of the
heart and small arteries which are radiating from it (Fig. b).If the egg is moved lightly, it is possible to see clearly the
rhythmic oscillations of the embryo.
On the contrary, an infertile egg appears completely transparent (clear), with a slight darkening where the yolk is. (a).
If during the candling operation, you find some eggs with a reddish spot stuck or attached to the shell, or a central
spot surrounded by one or more concentric hoops, or something nebulous crossing the inside; then in this case, the
embryos are either false or dead, and must be taken out of the incubator to prevent them contaminating other eggs
with bacteria by infection or explosion.
