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 wi&y necessary to ceil inside,

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 xloors 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 watgr. 



They should admit of easy opening and closing with a minimum 



joss 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" 



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



side and will close automatically as the attendant passes 



*bemg held in place by friction stops. All doors should be_raieiL 

 the floor at least eight inchest 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).
