and other unsanitary practices of broody hens and pullets are easily pre- 

 vented by boarding up just back of the runway where the hens enter the 

 nests, and allowing the fowls entrance to this runway only through trap 

 doors at each end, which are closed at night. (Fig. 63.) 



Trap nests can be fitted either into nests beneath the droppings plat- 

 form or against the wall. Working plans and illustrations of the improved 

 Cornell trap nest can be obtained from Circular i of the Department of 

 Poultry Husbandry, or from a later publication on " Poultry-House 

 Appliances." 



Fig. 48 shows eight methods of constructing roosting and nesting 

 arrangements. Fig./48-^ is desirable when the walls would harbor mites. 

 It must be built firm to prevent swaying while being cleaned. It has

the advantage of simplicity and cheapness. Fig. 48-5 is a compact and 

 complete arrangement. In both Fig. 48-/^ and B the perch rack rests on 

 the platform which brings the perches near the droppings. During cold 

 weather fowls occasionally roost on the platform instead of the perches 

 to keep warm and these become soiled. Fig. 48-C is too complicated and 

 expensive. In Fig. 48-Z} the nests are too low for convenience in gath- 

 ering the eggs and a hiding place is furnished for hens to nest on the 

 floor, where the eggs would not be easily discovered. Fig. 48-D has the 

 added disadvantage of occupying valuable floor space and being colder, 

 since the air is usually coldest nearer the floor. Fig. 48-^ does not pre- 

 vent the droppings from being scratched from the platform and does not 

 provide for nests. Fig. 48-F is the most undesirable of all because it 

 permits the droppings to fall upon the floor, thus soiling the litter and
