in addition to the windows, while in
) Others the ventilation is controlled en-.
} tirely by the latter method. The essen
tial features are to keep the air in the
room frsh and sweet. Muslin screens on
the windows provide good ventilation
without draft and at the same time keep
Ithe sun from shining on the machines.
Many incubator cellars have cement
floors, which are easier to keep clean
and neater than dirt floors
Setting Up and Operating Incubator.
Set up the incubator according to the
manufacturer 3 directions, and see that
the machine is perfectly level. If a
spirit level is not available, long shall
low pan of water set on top Of the in
cubator can be used as level to assist
in setting up the machine. Be sure that
all parts of the incubator are in their
proper positions and that the regulator
works freely. Do not plane off the door
Of the incubator, if it sticks, until the
machine has been heated up and thor
oughly dried Run the machine at about
lo2 degrees F. for day before put
ting in the eggs. It takes several hours
for the machine to come back to its
correct temperature after the eggs are
first put in; therefore the regulator
should not be touched during that time.
See to the regulation onf the tempera-
ture Of the incubator before opening
the door of the machine to attend to
the eggs Look to the care of the in
cubator carefully and regularly, but do
not change the regulator any more than
is absolutely necessary. The eggs tend
to throw off more heat as the embryo
develops, so that it may be necessary
occasionally to change the regulator
slightly. The temperature of the egg
chamber may be regulated by lower
ing the flame of the lamp in the middle
of the day where the room is subject
to considerable rise in temperature.
The machine should receive care enough
so that the temperature remains nearly
even. Most operators tend to their in
cubators two or three times daily, and
occasionally make extra trips as condi-
tions require them. Incubators require
careful and regular attention, which,
though simple, is very exactine. II at
tended to regularly ineubators do not
take much time, while neglect will gen.
orally show its effects on the hatch.
The Correct Temperature.
The correct temperature depends upon
the position Of the thermometer in the
egg chamber. The manufacturer di-
reetions should be followed and changed
only after considerable experience in
dicates that they can be improved. The
need of this change may be due to the
fact that manufacturer can not make
a machine and rules which win be
adapted to all conditions. When the
bulb Of the thermometer rests directly
on the eggs the temperature is usually
held at l01i degrees to 102 degrees +.
the first week, 102 degrees to 103 de-
grees y. the second week, and 10S de-
gress y. the third week; while hang
ing thermometer is operated at about
1oa degrees to 1904 degrees y. the first
two weeks and 103 degrees F. the last
week. At Matching time the machine
viii frequently run up to 104 to los do
gress r. without any injury to the chick
ems. II the temperature has been right
up to Matching time, it is usually better
not to change the regulator at that time,
provided the temperature does not run
up above los degrees F. While the eggs
will hatch just as well if the tempera-
ture is run slightly higher than noted
above throughout the hatch, the chick
ems are apt to be wea' and hard to
raise. In q good hatch the eggs viii
start to pip ON the evening Of the nine
teenth day, and most Of the chickens
will be out of the she'll on the morning
Of the twenty-first day. If the hatch
is much earlier or later than this it
indicates that the conditions during in
cubation have not been right. A high
temperature may hatch too quickly and
produce weak chickens, while con.
tinuous low temperature throughout the
hatch win delay it for several hours.
