Standard Classifications. — As was previously mentioned

 table gives a skeleton outline of these breeds. For a more 

 detailed description the student is referred to the "American 

 Standard of Perfection, " published by the American Poultry 

 Association. This book should have a place in every 

 poultryman's library. The preceding table gives eleven of 

 the standard classes. 



Utility Classification. — Utility classification is so termed 

 because it is based on the type and the value of the commer- 

 cial products yielded. The common breeds of domestic 

 fowls fall into one of four utility classes : Egg breeds, meat 

 breeds, general purpose breeds, and miscellaneous breeds 

 (Fig. 33). 



Examples of egg breeds are the Leghorns, Minorcas, and 

 the Anconas. These birds are distinguished by an active, 

 nervous temperament, possess great powers of flight, and are

 early; Leghorns often grow their main tail and wing feathers
