vided with some system of ventilation
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
the 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
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
has been heated up and thor
oughly dried. Run the machine at about
l02 degrees F. for day before put
ting in the eggs. 1t takes several hours
for tho 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
may be regulated by lower
ing the flame of the lamp in the middle
Of the day where the room is subject
10 q considerable rise in temperature.
The machine should receive care enough
30 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-
lions require them. Ineubators require
careful and regular attention, which,
though simple is very exacting. II at
tended to regularly ineubators do not
take much time, while neglect will gen
orally show its effects on the hatch.
Tho Correct Temperature.
The correct temperature depends upon
the position of the Thermometer in the
egg chamber. The manufacturers di-
rections 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 q manufacturer can not make
I machine and rules which will be
ADAPTED to all conditions. When the
bulb Of the thermometer rests directly
on tho eggs the temperature is usually
held at 1O1} degrees to 1o2 degrees +
tho first week, 102 degrees to LOB de
grees r. the second week, and lob DC
grsss r. the third week; while hang
Ing Thermometer is operated at about
los degrees to 1924 degrees r. the firs'
two weeks and 1O3 degrees F. tho las
week. At Matching time the machine
will frequently nun up to 1O4 to los Dc
gress F. without any injury to the chick
ems. If the temperature has been righ
up to Matching time, it is usually bette
not to change the regulator at that time
provided the temperature does not rur
up above los degrees F. While the egg
will hatch just as well if the tempera
ture is run slightly higher than notet
above throughout the hatch, the chick
ems are apt to be wea' and hard t.
raise. In good hatch the eggs vii
start to pip on the evening of the nine
teenth day, and most of the chickens
will be out Of the shell on the morning
Of the twenty first day. If the hatcl
is much earlier or later than this i
indicates that the conditions during in
cubation have not been right. A higl
temperature may hatch too quickly an'
produce weak chickens, while a con
tinuous low temperature throughout tn
match will delay it for several hours.
