Factors of Location Affecting Production.—A mild temperate 
climate is ideal, although poultry is managed successfully under 
a great range of climatic conditions. Factors of temperature 
should receive careful consideration. Extremes should be avoided, 
and locations which are characterized by rapid variations are 
undesirable. In the southern part of the United States, where 
average temperatures are high, conditions are less desirable than 
in the more temperate climates farther north. Canadian condi- 
tions, although very cold, seem to be superior to the extreme 
torrid climate of the South. There is no one best latitude; ideal 
conditions will usually be found in the latitude of Massachusetts, 
New York, New Jersey, Ohio, Indiana, Missouri, and through

to the Pacifie Coast. The prevailing wind direction should be 
determined, and the character of weather which it brings will 
materially affect climatic conditions. Prevailing winds from over 
the land are most desirable, as the associated climate is usually 
dry. North to northwest winds are best. Atmospheric conditions 
should also be considered. Close proximity to large bodies of 
water, to low river valleys, or to the ocean usually means a rela- 
tively high humidity, which is undesirable. For example, the 
Jersey coast, being close to the Atlantic Ocean, is handicapped 
by the presence of thick fogs during spring and fall, which means 
the prevalence of considerable roup and canker during these 
seasons, while central New York State or North Jersey, being 
removed from the water, has a drier climate and less trouble from 
atmospheric moisture.
