why do chicks die and stick in shell
in incubator" This question is asked
time and again. In natural incubation
the eggs are in contact with the body
Of the setting hen-that is the heat
source while they, the eggs, receive
the outside air thru the feathers Of the
old bird and porous walls Of the nest.
Here we have two sources Of supply
1.-TWO opposites) heat and air. The air.
is diffused thrus feathers and porous
nest amongst the eggs without draft.
In artificial incubation the eggs lie on
a tray in hot air only and in a draft.
Hot air contains much less oxygen
than cool air. consequently anything
that inhales hot air has its digestion
impaired and develops poorly.
This is the main cause why incuba-
tor chicks stick and die in the she'll
This is why the albumen, white Of
egg, instead of becoming chick. is
formed into glue. This is why chicks
are frail and the draft Of air finishes
them. OF course there are many minor
causes even under hen; there may be
too much heat or cold; eggs from poor
stock, too much or not enough mois-
ture, etc. When hen steals her nest,
and is not interfered with, she matches
every egg. So will a robin or crow.
There are no infertile eggs from wild
BIRDS and they hatch every egg, and
raise every one of their young. Study
nature and learn properly
Some Of our latest improved incuba-
tors are using this diffusion idea as it

the meantime it is we'll that the be-

Some Rules For Guidance.
There are number Of rules that ap-
ply to all makes. and it will be we'll
for the beginner, to acquaint himself
with them. They may be briefly stat
ed as follows:
Fill lamps in evening. Never use oil
less than $50 degrees test.
Begin each hatch with new wick.
Keep the machine as near 10S de-
Dry cellar Is the best place for
Matching
Never trim wick; scrape Off the
charred part.
The incubator room must be ventil-
ated, but have no drafts.
Never allow the lamp to become
empty.
Test eggs at end of first week.

required. Turn eggs night and morn
ing, beginning on the fourth day.
Keep the burner free from dirt.
Never add eggs after the incubator
has Matched.
Do not allow the flame Of the lamp
to be turned up so high that it will
sEncke -
In placing the eggs in the incubator
see that the large ends all point the
same way in the trays.
Begin cooling eggs once daily after
the fourth day. ending when 1t is no.
ticed that the eggs are piping.
After each hatch thoroughly clean
and funigate the incubator. While
you are turning or cooling the eggs
keep the incubator doors closed.
A mixture OF white and brown eggs
gives a very unsatisfactory hatch. 4.
In cooling eggs place Thermometer
on them after they have been turned
and when s. degrees is reached return
the tray to the machine.
The dryer the air the more rapid IL
evaporation. w
After removing the infertile eggs
from the machine spread out the fer
tile ones so that they occupy about the
same relative position to one another.
Never removeechicks from the incuba-
tor ut night .s.l X b. 3
