Ventilation. This is an important matter, because it is 

 known that the presence of moisture impairs the health of 

 fowls. Fowls throw off quantities of moisture when exhal- 

 ing and this moisture, together with that which originates 

 from any other source, must be carried out of the building by 

 means of ventilation or currents of air. These air currents, if 

 rapid, cause drafts and drafts in the house endanger the 

 health of the fowls. To prevent these drafts the air must be 

 allowed to enter through the one side only by opening the 

 windows, much or little, according to the temperature and the 

 force of the incoming wind. In some localities, cloth covered 

 frames are placed in openings between the windows and high 

 enough up in the side of the house so that when these frames, 

 which should be hinged at the top, are opened the drafts can 

 not strike the fowls on the floor. These cloth covered frames

Windows hung on weights and pulleys serve as ventilators when 

 required. Openings above windows fitted with two sets of doors, each 

 of which can be closed or open, provide constant ventilation.
