EXERCISE 24 

 THE BROODER— LOCATION, CONSTRUCTION, AND OPERATION 



Object. — To become familiar with types and sizes of brooders, methods 

 of locating and operating them, capacity, fuel, and temperature control. 



When possible each student should run at least one machine for the 

 first three weeks of a brooding period as supplemental to the work of this 

 exercise. 



Equipment. — Access to a complete brooding equipment, including long 

 pipe brooders as well as small and large colony stoves and kerosene hovers. 

 (This study may be extended by visiting near-by poultry farms and studying 

 prevailing types of brooding equipment.) 



Procedure. — Stey 1. — Make a classified list of all brooders studied on 

 the basis of the fuel supply — kerosene, coal, gasoline, and fuel oil. 



Step 2. — Make another classification of colony stove brooders on the 

 basis of capacity, fifty chicks, one hundred, three hundred, five hundred and 

 one thousand chicks; also include cost of each in this classification. 



Step 3. — Examine each stove brooder, noting its general plan of con- 

 struction, such as external appearance, durability, simplicity, fuel supply, 

 presence or absence of hover curtains. Classify stoves studied according to 

 presence or absence of curtains. 



Step 4. — Raise hover of a typical stove and study the details of con- 

 struction, heat regulating device, damper control, location of thermostat, 

 construction of grate, size of fire pot, and capacity of coal chamber. 



Step 5. — Note the size of room or rooms in which the stoves are operated 

 and what precautions are taken to keep chicks from crowding. 



Step 6. — Classify mammoth pipe brooders on the method of distribu- 

 tion of heat to the hover area; as, overhead pipes or drum-heated circular 

 hovers. 



Step 7. — Note the construction of the long brooder house, the division 

 into pens, the size and number of heated pipes and their arrangement for 

 control of heat. 



Step 8. — Study in detail the various types of kerosene-heated hovers, 

 noting design, location of lamp, size of hover, capacity, portability, ease in 

 attendance, and durability. 



Step 9. — Make a record of all machines studied according to the fol- 

 lowing form:
