not be such a large amount of air space for the 
fowls to warm with their bodily heat.

with small glass seriously obstruct the light, while 
very large glass break too easily and are more 
expensive. 
While the exercising part of the poultry house 
should not be too warm, so that the birds may be 
Roosting induced to exercise in order to keep 
Quarters warm, they cannot handily move 
around while on the roosts, and this part of the 
house should be the warmest and most snug of all. 
However, there is no necessity for having a sepa- 
rate and more tightly constructed room, apart from 
the exercising quarters, for the location of the 
perches. With the roosts in the rear part of the 
house, and that part of the house the lowest as 
I have suggested, there usually is no necessity 
for any separation of the roosting and exercising 
parts of the house in the more pleasant sections 
of America. However, in cold climates, or with 
birds that have very large combs, it often becomes 
desirable to hang curtains of burlap or a similar 
loosely woven material down in front of the 
perches at night, but that is ordinarily as much
