CHAPTER XXIV 



BROODING 



Brooding may be done by one of two means : First, by natu- 

 ral brooding or by the hen; second, by artificial means by 

 either cold or heated brooders. Heated brooders may be run 

 by oil, coal, gasoline, gas, or electricity. Hard nut coal is 

 used in coal burning hovers and incubators.

In artificial brooding the following conditions must be taken 

 under consideration : A compartment in which the temperature 

 is under control. Dryness and a constant supply of fresh air 

 are essential. A brooder may be of two kinds — that is, an 

 indoor brooder or one kept inside a building, providing a run, 

 and the outdoor brooder. The outdoor brooder is provided 

 with two compartments, one compartment having a cooler tem- 

 perature than the other, to which the chicks may escape for 

 food, exercise, and a sun-bath. Sufficient space and sunlight 

 must be provided. Safety from fire and protection from ene- 

 mies, as cats, hawks, crows, and skunks. 



Frequent disinfection of the brooder and feeding and water- 

 ing utensils are necessary. The second compartment of the 

 outdoor brooder is the warm-air compartment, provided with
