POULTRY HOUSE CONSTRUCTION 
Plenty of light is necessary in a poultry house; 
sunlight not only carries warmth and good cheer, 
but also tends to arrest disease. But, 
while too much light is impossible, 
there is such a thing as too much glass in a poul- 
try house; not only because it makes construc- 
tion expensive, but also because it makes a house 
too cold at night and too warm in the day- 
time, for glass gives off heat at night as readily as 
it collects it in the daytime. 
Windows should be placed comparatively high 
up in the walls, and the greatest length should be 
placed up and down, not horizontally. The time 
when sunshine is most needed is when the sun is 
the lowest, that is, from September 21 to March 
21; therefore the necessity for having the windows 
up high enough that the sun may be reflected well 
back in the pens, as otherwise only the space directly 
in front of the windows will be reached by the sun. 
Following out this idea, the windows in a nar- 
row house need not be placed so high as in a house 
having a greater depth, and consequently the walls 
would not need to be so high. In a house ten feet 
deep the highest point of the windows should be at 
least four and one-half feet from the ground; while 
seven feet should be the extreme height with a 
house fifteen or sixteen feet deep. 
If the front wall is made high, make the rear 
wall comparatively low, and the house will be
