chicks pant Allow thcm 20 remain
in the incubator the first "A to 36
hours. and during this time they
should not be given anything 10 eat
or 20 drink.
DO Not Turn the Eggs at Matching
The eggs should Doe turned for the
last time the evening Of the eight.
ocuth day IL is very bad practice
TO turn the eggs after they have
commenced piping, In fact that
practice might cause the chick 20 dry

make another way OF getting out.

not want to be disturbed II this

Relation 20 Heat 10 Moisture.
Experience seems to Indicate that
/ heat requires low moisture and tow
heat requires high moisture. For
! this reason you must need more
moisture In cold weather, as the cir
| ouation of air is not as rSpid In
| warm as In cold weather, which also
/ has a relationship 70 moisture and
| ventilation.
In high attitudes. the operation Of
| incubators ia a different story. Most
| incubators are manufactured around
tho Great Lakes region, and rules for
operating them are based on the aC-
compnnyiug atmospheric conditions.
I'm high attitudes IL Is necessary TO
add much more moisture. Tho lncu-
bator room should be flooded twice
each day. 1t may even be noces-
sary to allow moisture inside tho ma
chine by sprinklng the eggs with
water. the same temperature as that
of the eggs--hy using moist sand
trays or sponges beneath the egg
! trays.
Too High Temperatures.
In sm1il-si2ed inCubdtors where
! the incubation temperature is 1903
/ degrees. we have found II wise not
ITO let the temperature at hatchlns
| time 20 above l05 degrees. and IL is
| better TO keep it between l03 and
/ 1O4 degrees at Matching time. IL the
. temperature is allowed to run much
over 1O4 degrees at Matching time
/ il Is sure 90 dry a large number OF
/ the chlc&s TO the shell and shell
membrane: hence a large number

heat generated by the chick in the
egg Is responsible for the tempcra-
ture having tendency to rise to-

Ventilation of OfiInCubator Room.
Many incubator operators never
