PRAIRIE FARMER'S POULTRY BOOK 



The semi-gable type of poultry house 



Types of Poultry Houses 



What type of a house is most suitable to the farm? The 

 shed roof has many friends. The advantages of this type are 

 several : It furnishes a large frontage by which sunlight can 

 be admitted to all parts of the building; it is more easily con- 

 structed and is less expensive than other types ; as the roof has 

 a northern slope it v^rill be more lasting than other roofs be- 

 cause protected from the direct rays of the sun. The shed roof 

 has the disadvantage that it is easily torn away and destroyed 

 by heavy ^yinds. When the wind strikes a sloping roof, its 

 force is resolved into two forces, one parallel to its surface 

 which has no effect, and the other perpendicular to its surface 

 which exerts a downward pressure and tends to hold the build- 

 ing in place. But when a high wind strikes the front side of 

 a shed-roof type of building there is no downward pressure 

 and, unless the building is carefully anchored, it will be torn 

 away by the wind. I have known shed-roof buildings to be 

 torn to pieces and scattered on a distant field while other 

 buildings with roof pitching toward the wind have been un- 

 moved.
