POULTRY HOUSE CONSTRUCTION 
Except in northern latitudes and exceptionally 
cold climates, single-walled houses are now much 
more popular than the double-walled 
ones—with perhaps a heavy packing 
of sawdust, earth or hay—which were considered 
quite necessary a few years ago. 
In climates where the temperature seldom falls 
below zero, a wall composed of one thickness each 
of boards and tarred paper or roofing fabric 
makes a comfortable house. This construction 
may be arranged in two ways. The cheaper plan 
is to place unmatched boards (sheathing) next to 
the studding and then cover the exterior with the 
felt. The other way is to place the felt next to 
the studding and cover with tongued-and-grooved 
boards. This makes the house somewhat more 
attractive on the outside, but there is no other 
advantage. 
In cooler localities the ideal construction of wall 
is, first, sheathing next to the studding, then a layer 
of tarred paper, and then cover with tongued-and- 
grooved siding. This is the kind of wall in use on 
the author’s plant, and makes a house warm enough 
for any breed and any section of America. 
A ‘combination roof” or a “ gable roof” re- 
quires slightly more material to construct than a 
““ shed roof,” but that is one of the least of several 
reasons why I prefer the latter kind. 
A shed roof is the easiest to build; 
it gives the highest vertical front exposed to the
