tight board wall should be laid first, so that the house can be easily 

 cleaned and kept free from vermin ; it will greatly increase warmth 

 in the winter. When it is desired to line the inside back wall of 

 the house, tongue-and-groove boards are the best. They should 

 be free from extra beading. It is rarely necessary to ceil inside 

 the roof of the poultry house, except perhaps over the roosting 

 places in cold climates. 



In the construction of intermediate walls or partitions, a good 

 method is to board the bottom part about thirty inches solid, the 

 remaining distance being covered with wire or cloth. The use 

 of cloth makes the building cheaper, but is less durable and collects 

 dust. In houses over forty feet long, one cross partition or more 

 should be put in to prevent a draft blowing through the house.

FIG. 75. Four styles, of doors for poultry houses. A, Brooder house door, cut in the 

 centre so that the top half only need be opened, providing ventilation but preventing floor 

 draft; B, door hung to swing both ways; C, double L doors for use where overhead trolleys 

 are used; D, sliding door. 



Doors. All doors in laying houses should be large enough to 

 permit the attendant to pass through quickly with feed and water. 

 They should admit of easy opening and closing with a minimum 

 loss of time. They should be so placed that the work can be done 

 with the least possible retracing of steps, and should be strong 

 and durable, as they are much used. The doors between pens 

 should be arranged in a straight line, hinging on one side with 

 double-action spring hinges, so that they may be opened from either 

 side and will close automatically as the attendant passes through, 

 being held in place by friction stops. All doors should be raised 

 above the floor at least eight inches, so that in opening and closing 

 they will be clear of the litter on the floor. The sketch shows 

 types and methods of hanging poultry doors (Fig. 75).
