A continuous house 20 feet wide 



Recently there has been a strong and constant tendency on the part of 

 the large commercial poultry raisers to build long houses with pens large 

 enough to accommodate 100 to 500 fowls. This practice is justified prin- 

 cipally because of economy in labor required in caring for the fowls, and 

 in the original cost of the building. 



A long house makes it possible to use labor-saving devices such as 

 trolley system, large hopper feeding and running-water devices, which 

 not only expedite work but also lighten the task. A trolley system can 

 be used for all feeding, for carrying eggs, for cleaning pens, or even for

FIG. 64. Cross-section of a pen 20 jeet deep 



carrying water when running water is not possible. This style of house 

 allows large numbers of fowls to be easily accessible. The work can be 

 done comfortably during inclement weather. 



The building shown in Figs. 64, 65, 66 is 20 feet deep and no feet 

 long. It is divided into five pens each 20 feet square and one feed room 

 at the east end 10x20 feet. The front of each pen is fitted with two 

 glass windows made up of two 6-li'ght io"xi2" and one 3-light 

 io"xi2" sash. This makes exactly one square foot of glass surface to 

 every 16 square feet of floor space. 



The glass windows are placed 8 inches above the floor and to the plate 

 6 feet higher. By bolting the three sash together with pieces of strap 

 iron, the windows can be hinged at the side and used both for summer
