Building Poultry Houses.

be yi pitch. Shingle roofs should generally be Yz pitch. Paper covered 

 roofs can "be flatter. 



Each form of roof has advantages and disadvantages. The single- 

 span roof is the easiest to build (Fig. 40-/-^). It gives the highest front 

 exposed to the sun's rays, which are 

 reflected back, drying the ground and 

 making a warm shelter. It throws all 

 the rain water to the rear, lessening 

 the length of eaves-trough one-half 

 and keeping the front of the house dry 

 where no eaves-troughs are used. It 

 allows the windows to be placed high. 

 A tarred paper roof will last many 

 years longer if the slope is toward the 

 north. The one-span roof is cooler 

 in summer if not exposed to the vertical rays of the sun. It is especially 

 recommended for houses not over 16 feet deep. The gable roof 



provides for a large garret 



- i||ft space which can be stuffed 



- irtft vvith straw, making the house 

 warmer and dryer. (tFigs. 35 

 and 40-C) The combina- 

 tion house shares in the ad- 

 vantage and disadvantages of 

 the others. (Fig. 40-^.) It

furnishes the best head room with the least cost for building material and 

 the least air space for a given height in front. 



To provide the necessary height 

 for sunlight in front and working 

 room in the rear, the combination type 

 saves siding material on the north 

 wall when compared with the gable 

 type, as will be seen by the distance 

 between plates in Fig. 37, and on the 

 front over the shed-roof type, as rep- 

 resented by the distance between 

 plates. Fig. 37. For houses 20 feet wide or more the gable (Fig. 40-C), 

 half monitor (Fig. 40-Zi), monitor (Fig. 40-D), or combination roof 

 (Fig. 40-B), is preferable. The half-monitor is desirable on very wide 

 houses that face the scmth, and especially when a central alleyway is, 

 necessary. The upper window throws the light far toward the rear. The
