INCUBATION 



In poultry, the reproductive process is accomplished 

 in two stages. The egg is first produced, developed, 

 fertilized within the body of the hen, and laid. Then 

 the egg is subjected to a certain temperature (100 F. 

 or a little higher) for about 21 da., during which time 

 the embryo develops and hatches out of the shell as a 

 chick. The process of developing the embryo within 

 the egg by means of heat is called incubation. When 

 this is carried on by a hen, it is known as natural 

 incubation; when incubation is accomplished by means 

 of a machine, oven, or other device, it is known as 

 artificial incubation. Man has little control over the 

 reproductive process in its first stage except so far as 

 the selection of the breeders is concerned; in the second 

 stage, however, if artificial incubation is practiced, he
