COOPS AND BUILDINGS FOR POULTRY

perpendicular space above the 

 lower roof, for the better light- 

 ing and ventilation of the rear 

 part of the house. Occasion 

 for introducing such features 

 usually indicates fault in the 

 general design of the structure. 



Walls. Walls of structures 

 for poultry should always be 

 perpendicular. This applies to 

 every form and size of house 

 or coop designed for poultry. 

 Whatever may be tolerated in 

 a converted coop or building, 

 the walls of one designed for 

 poultry should be perpendicular. 

 When one function of the 

 glass window was to warm the 

 interior of a closed building 

 by the sun, houses were built 

 with sloping front walls, in 

 order that the windows might 

 be placed at the angle that 

 would make them most effec- 

 tive for that purpose. This 

 form of construction was un- 

 satisfactory, even when it had 

 supposed advantages. 



Floors. Within the same 

 walls and under the same roof, 

 floors should be on the same 

 level. They are always made 

 so in small buildings, but when 

 long houses are placed on 

 ground which slopes with the 

 length of the house, builders 

 sometimes make a building 

 with roof following the slope
