eggs. Simply run the machine empty
for a day or two in order to ascertain
what adjustment of the lamp and regu-
lating device is necessary to maintain
the desired temperature If a uniform
reading of the thermometer can be held
for two days there can. be no fault In
the machines equipment, whereupon 1t
is safe to begin business.
Fill the egg trays conveniently full
without overcrowding. Crowded trays
mean trouble in turning the eggs pos
sbly breakage. Place the eggs on their
sides, never on end See that the Their
mometer has the proper relation to the
eggs, as prescribed by the makers of
the incubator. Close and open the door
to the egg chamber as gently as pos
sible. Earring and banging might dis
turb the adjustment of the regulator or
lamp. Once the hatch is started don't
open the door to read the thermometer.
! because In SO doing the egg chamber will
lose too much heat. Don't be alarmed
at the fall In temperature when eggs are
first put in the machine. Remember the
eggs are cold, probably they have tenn
perature of 81 degrees. and perhaps Is
hours may be required to bring them up
to the desired temperature.
For the first three days after the eggs
have been placed in the machine little
attention is required save the daily ALL
ing and trimming Of the lamp. As COM
mon sense dictates, this must be done
punctually; a good plan Is TO set aside
! a particular time each day for this work.
Morning is the best time because there
is then all day in which TO note the be-
havior of the lamp.
Use a good grade of kerosene. Wipe
the bowl Of the lamp and all parts Of
| the burner free of oil. rub the charred
portion of the wick and keep the drafts
i clear Endeavor to have nicely round
; ed fame. Avoid the fish tail flame; the
points are Jiliely to smoke When re-
| placing the lamp in the heater after
cleaning do. not start the flame too high.
AS the heat Increases the flame will
| mount of its own accord. Allow for this.
RULES FOR TURNING EGGS
on the evening of the third day and
twice daily thereafter the eggs should be
turned. This Is necessary that the de-
! veloping embryos will not gravitate and
| adhere to the membranous lining Of the
! shell. 1t also permits of a more uniform
| development. Some incubator operators
| turn the eggs three or four times day.
| probably on the assumption that the hen
turns her eggs frequently. Experience
has shown. however. that two turnings
a day will give good results.
! To perform this work, remove the trays
from the machine. and II convenient place
| the trays on top of the machine. While
| turning the eggs see that the door to
the egg chamber is closed You cannot
afford to allow the interior of the ma
1
turn each egg an exact half revolution,
merely aim to alter the position of the
: egg.
If the trays are divided in the middle
| and built with a slight incline toward
the center, the easiest way to turn the
! eggs is to remove the two middle rows
roll the others gently toward the center
using the palms Of both hands, then re-
place the middle eggs at the outside ends
\ of the tray. The operators hands should
be clean, particularly free from kero-
] sene. therefore, 1t is best to turn the
eggs before trimming the lamp.
When the tray is replaced it SHOULD
be reversed end for end. If there are
two trays to a machine. which is Gus
! tomary in the larger sizes, the trays
should be alternated from side to side
| as well from end to end Thes,
| changes are made so as to equalize any
irregularity in the temperature of tn,
egg chamber. 1t sometimes happens tha
one part of the chamber is slightly
warmer than another. In which event. il
the eggs and trays are systematically
| changed about. the distribution of hea
! is made uniform.
Certain makes OF incubators are fitted
with mechanical devices for turning the
eggs. In large machines having capaci
ties Of several thousand eggs, this fea
ture means a great saving in time. An
other method of turning is to invert al
empty tray over the loaded tray, ant
with quick. def movement revolve tn,
two trays upside down. This is possibl,
only with certain types of trays
