BROODING OF CHICKS 113 



Chicks that contract ailments of any kind should be 

 isolated immediately. 



A critical stage in the life of chicks is when they are 

 feathering, and at this time they should be supplied 

 with an abundance of nitrogenous foods. 



MAMMOTH INCUBATORS AND 

 BROODERS 



The Mammoth system of incubating and brooding has 

 been so well developed that it can now be used with 

 perfect safety. Incubators are built in sections and have 

 a capacity of from three thousand to many thousand 

 eggs. It is not unusual to see one Mammoth machine 

 containing 15,000 eggs in operation. These incubators 

 are heated by self-regulating coal-burning furnaces, the 

 heat from which is distributed by means of hot water 

 that passes through a system of pipes so adjusted as to 

 keep a continuous flow, or circulation, from the furnace, 

 through the pipes, and back to the furnace again. The 

 heat in the egg chamber is regulated through the raising 

 and lowering of the egg trays and by an automatic or 

 thermostatic regulator. In writing of this system, one 

 familiar with it says that the simplicity, economy, 

 and safety of this type of heater is now universally 

 recognized. 



A system of hot-water heating is used with the Mam- 

 moth brooder. This system can be used with either a 

 single- or a double-row brooding house. The system for 

 heating is much the same as has always been used in 

 hot-water brooding systems. The one great difference 

 is that by using the self-regulating coal-burning furnace 

 better service can be obtained at less cost than when 

 boilers are used. Complete information regarding this 

 system of incubating and brooding can best be obtained 

 from those who manufacture the apparatus.
