SUCCESS IN POULTRY CULTURE 
but such statements are, to say the least, 
misleading and should not be heeded by 
those who desire to get the best results 
from their incubators. Nature seldom 
sets a hen in cold weather, and when she 
does the hatch will be a failure unless man 
provides protection for the nest during 
the incubating period. : 
To get the best results from an incu- 
bator in cold weather it should be sur- 
rounded with conditions that imitate, as 
near as possible, those conditions found 
in nature during the natural breeding 
season of the fowls. Those conditions are 
not found in a room in which the tempera- 
ture sometimes falls as low as zero; which 
is the case when February and March 
hatches are attempted, in a cold climate, 
in a room that is not well insulated. Even 
in many of the warm climates the morn- 
ing temperature often falls below the 
freezing-point early in the hatching sea- 
son, and if the incubator-room is not well 
built and well insulated, the temperature 
in the room will fall nearly as low as the 
temperature out of doors. 
No matter what incubator you are using 
or intending to use, don’t let anybody talk
