ing the final period when the
chicks are emerging from the shells.
Ii is not necessary to keep the eggs
at a constant temperature of 1O2 IL
degrees, but this should be the OBJ
ject aimed at, and at least the av-
erage temperature for each day or
week and the hatch.
OF course. the sitter cannot main
tain an inyariable heat of 102 IL
degrees for every egg every hour OF
the Matching period, but it is be-
lieved that each egg averages this
temperature each day. IL can be con-
servatively stated that a sitting hen
turns her eggs, at least 10 times a
day, rolling the outside eggs to her
breast and changing the position of
each egg i'm the nest. This rolling
takes place the first day the hen sits
on the eggs.
Fill the incubator in the morning
and turn the eggs that evening, and
continue turning them morning and
evening until the first chick pips
the she'll Three turnings a day are
pracuced in Egypt and by some
American operators. The noon turn
ing could not be harmful. and il
might be beneficial but so far as we
know no experiments have been
conducted TO decide this question
of additional turnings.
Test the eggs at the end OF the
first and second weeks and remove
the infertiIe eggs and dead germs.
The egg chamber of the ircuba-
tor is warmer at the center than
near the door, and, To overcome
this variation, the center eggs are
frequently lower or farther from the
heating compartment. However, this
uneven heat is not injurious when
the eggs are moved around the egg
chamber of the machine similarly
10 their movement under a hen. II
the incubator tray has no divisions,
place the center eggs at the front
and back OF the tray and roll the
remaining eggs toward the center.
II the eggs are i'm rows on the tray,
keep moving the outside eggs of
each row 10 the center. When there
are two trays, sniff them from side
TO side of the egg chamber and turn
them end for end alternately. there

the incubating temperature of each
egg.
Leave the eggs out TO cool and air
at each turning until they are al
most cold. Fifteen TO 20 minutes is
Lot too long 10 cool the eggs in
warm weather. Commence cooling
and airing the eggs ia this manner
at the first turning and continue it
az each turning until the first egg
is pipped. Keep the door of the
egg chamber closed while the eggs
are airing.

water over the eggs and tray with
g. whisk broom. Open the ventila-
tors throughout the hatch. Do not
place tray OF water under the
eggs as it is an ideal medium for
the development Of mold. the spores
of which fungus cause one form of
white diarrhoea in baby chicks.
The egg chamber must be filled
with moist air when the chicks are
piping the shell on the 18th and
goth days OF incubation, otherwise
the shell membranes tsNins inside
the shelD become dry and tough
and many chicks are imprisoned.
Pure air is also necessary at this
critical time. The sitting hen eX-
poses the pipped eggs constantly to
