some of the glass windows and substitution in their place 

 of muslin windows. The fresh air movement led in many 

 cases to the entire front of the house being left open. Prac- 

 tice seems to be generally uniform with regard to the desira-

 and egg production is well maintained. 



The Modern Standard Type. The modern standard type 

 of poultry house is one built rather low with a shed roof. 

 The back and side walls are solid, the front largely open. 

 About two-thirds of the open area is covered with a muslin 

 curtain, and one-third with glass. This glass is provided

 all of the state Colleges hi the land, and is found on most 

 of the large and successful poultry farms. 



Roofs. The roof is an important feature of the poultry 

 house, because it is rather expensive to build. Three types 

 are common; the shed roof, the gable roof, and the broken 

 span. The shed roof house is all of one pitch. The gable 

 has two pitches at the same angle, with a ridge in the center. 

 The broken span has two pitches, the back slope being much 

 longer and extending to a lower point than the front one. 

 Houses of the shed roof type are most popular, for the 

 reasons that they are cheapest to build, they require less 

 lumber, have a higher front, and therefore, admit more 

 sunlight, and all rain water is carried off behind (Fig. 112).
