PROPER VENTILATION 



The most important feature in a poultry house is 

 proper ventilation. An efficient system of ventila- 

 tion affords an abundance of fresh air without 

 drafts. Fresh air keeps the house pure and dry. 

 Nothing will cause disease more readily than a damp 

 house or one which has a foul odor. 



There are several ways to supply ventilation, but 

 the simplest and least expensive is to have an open 

 or muslin covered front. These open fronts on 

 the houses should be protected in some way to pre- 

 vent the rains and snows from being blown into the 

 interior. It is a good plan to attach an awning 

 made of wood or some other light material, arranged 

 in such a manner that it can be lowered or raised. 



Muslin will keep out the snow and rain to a 

 certain extent, but when it gets wet the cloth loses 

 some of its merit as a ventilator, as damp muslin 

 will not permit a free passage of air. By protect- 

 ing the muslin with an awning it will not be affected 

 in that way. The muslin should be put on a frame 

 so that it can be removed on a pleasant day, allow- 

 ing fresh air to circulate through the house on such 

 days.
