LONG LAYING HOUSE OF SMALL UNITS 



133 



It will be noticed that a door is in the front of each pen (Figs. 

 86 and 87) ; this is necessary in a house to be used for educational 

 and experimental work, but is not desirable in a farm poultry- 

 house where one attendant will care for the entire flock. The 

 muslin curtain should then be extended to cover this space. 



Attention is called to the presence of an elevated walk in front 

 of the house, to allow easy access to each pen and yet allow the 

 birds to enter the yards which extend to the south or front side. 



Fig. 87. — Long laying house as planned in figure 86. The small units are suitable for 

 breeding purposes. 



Note the hinged clapboard on the outside of the back wall, 

 which can be opened and thus allow air to circulate around the 

 perches on hot summer nights (Figs. 67 and 86 j,*
