M OST BOYS AND GIRLS when joining a poultry club 
begin their work on a small scale by carrying on their 
hatching operations with sitting hens. Accordingly, the direc¬ 
tions in this bulletin are given for the use of beginners or those 
wishing to hatch eggs by the natural method. 
For information on the artificial incubation of eggs, as well 
as for additional and more complete information on natural 
incubation, the reader should ask for Farmers’ Bulletin 585, 
“Natural and Artificial Incubation of Hens’ Eggs,” which may 
be obtained in many cases from local club agents or will be 
sent free of charge on application to the Division of Publica¬ 
tions, United States Department of Agriculture, Washington, 
D. C.
