MASSACHUSETTS OPEN PIPE BROODER HOUSE 



A Popular Type of Brooder House for Extra 



Early Chicks. Used Quite Generally in 



New England. Hot Water Pipes 



Not Enclosed. 



By PROF. J. C. GRAHAM 



(A type of hot-water pipe brooding house in general 

 use in New England, where it has given excellent results 

 for many years, is known as the open-pipe system. One 

 of the most modern and best planned houses of this kind 

 is the. one designed and in use at the Massachusetts Agri- 

 cultural College, which is described by Prof. Graham as 

 follows. This house is illustrated in Figs. 142 and 143. 

 Ed.) 



This house is designed for early or winter brooding 

 by people who wish to brood in large numbers. It is 14x72 

 feet. Twelve feet at one end is used for the pit, furnace, 

 coal, etc. The other 60 feet are divided into 12 pens, each 

 five feet wide, as shown in detail in Fig. . It is heated by 

 hot water, the pipes running parallel with the floor. The 

 floor has a fall of 15 inches toward the pit. This gives a 

 good chance for flow and return. The walls, both front 

 and rear, are 6^4 feet high. 



The house is lathed and plastered on the inside with 

 wood pulp plaster. This gives a very hard, smooth finish 

 and is about as cheap a method of construction as one can 

 use for a good finished piece of work. In the ceiling there 

 are tbree openings, each about 15x24 feet. These are for 

 ventilation particularly. Over these are placed burlap 

 screens or small doors. 



As can be seen, it has a good cement foundation and
