The ventilation of a poultry house is very important. A house 

 with tight walls, roof and floor and an open front, will contain cold, 

 dry, and pure air, three essentials for the health of the fowls in 

 winter. With such a construction there will be no draughts, but 

 plenty of fresh air. Cloth curtains on the front openings can be 

 dropped on cold nights or during stormy weather, and a glass win- 

 dow will allow entrance of light at all times. Many cases of colds 

 have been cured by removing the south side of the house and al- 

 lowing sunshine and cold, pure air to enter. Hens must not freeze, 

 neither do they need to be kept too warm. 



In the summer time a ventilator in the back of the house is 

 opened. Air enters this and goes up between the studding and 

 Drafters through the hood, above the heads of the fowls. This al- 

 lows circulation of air, thereby allowing the warm air to escape, 

 in the summer, without a draught on the chickens' heads. To allow 

 for this air passage the back plate is cut out between three stud- 

 ding. See illustrations on pages 6 and 8. 



It is not advisable to use ventilator shafts or other devices ta 

 insure ventilation. In fact many houses that have proved satisfac- 

 tory in every way have no ventilating schemes whatever, nor any- 

 roosting hood.
