72 METHODS OF POUI.TRY MANACEMENT. 



frame covered with lo ounce white duck is hinged to the top of 

 the front opening and covers it Avhen closed down. This cur- 

 tain is easily turned up into the room, where it is caught and 

 held by swinging hooks until released. 



The roost platform is made tight and extends along the 

 whole length of the room against the back wall. It is 4 ft. 6 in, 

 wide and 3 ft. above the floor, being high enough for a person 

 to get under comfortably when necessary to handle or catch the 

 birds. There are 3 roosts framed together in two 15 ft. sec- 

 tions. The tops of the roosts are 81-2 in. above the platform 

 and hinged to the back wall so that they may be turned up out 

 of the way when the platform is being cleaned. The back 

 roost is 7 in. from the wall and the spaces between the next 

 two are 16 in. They are made of 2 by 3 in. spruce lumber on 

 edge with the upper corner rounded off. 



In every pen there is a door placed 5 in. out from edge of 

 the roost platform. Fifteen trapnests are placed in three tiers 

 against the partition in each end of the room. The trapnests 

 are described in a subsequent section of this bulletin. 



Troughs similar to those described on page 40 are used for 

 feeding mash, shell, bone, grit, and charcoal. 



There is a walk outside of the building which extends along 

 its entire front. It is 4 ft. and 8 in. wide and made of 2 in. 

 planks and is on the level of the floor of the building. 



Detailed working drawings and specifications for one section 

 or unit of this curtain front house follow. From these data 

 anyone can figure what the cost of building one of these houses 

 of any desired length at the prices of building material in his 

 locality.
