about 2 or 3 feet from the floor. This will give sufficient heat for the 
house aucl keep the birds comfortable. These pipes may be connected 
with the same heater used for running the warm brooder pipes. In 
the Northern States, in extremely cold weather, raisers also use the 
heating pipes in the warm brooder house in addition to the cold brooder 
pipes. 
An excellent plan is shown in fig. 20 for the arrangement of the 
heater for connecting the pipes in the warm and cold double brooder 
house. It will be seen that the heater is nlaced in the center of the 
M. 
building; the warm brooder 
house is shown on the right 
and the cold brooder house 
with runs attached is shown 
on the left, and pipes, indi¬ 
cated by dotted lines, run in 
both directions. This is the 
most economical house to 
build and lessens the work 
in attending the stock. The 
room in the center of the 
building will be found very 
useful and is generally used 
as the feed room. The heater 
is in the cellar beneath this 
room. This plan is used by 
one of the largest and most 
successful raisers of ducks 
on Long Island, and it has 
his highest indorsement. 
The building may be of 
any size, the plan being as 
successfully carried out on 
a large scale as on a small 
one. If a small building is 
used at first, it may be en- 
larged on either end to suit 
the growing business, and 
extended upward of 100 feet 
in either direction, thus making the building more than 200 feet in 
length. The heater must be considered, when put in, with this object 
in view. A heater capable of heating the 200-foot house can easily be 
regulated to heat one of 50 feet, but a heater that will heat properly only 
a 50-foot or 100-foot house would be insufficient to heat the larger one. 
Another difference between the cold brooder house and the warm 
brooder house is that the former has outside runs attached. These runs 
are used for feeding and watering when the weather permits, instead of
