Poultry Flock Improvement 



By J. C. Graham 

 VIRGINIA AGRICULTURAL EXPERIMENT STA2J> 



Many commercial poultrymen in the State are anxious to develop a high degree 

 of efficiency in their flocks but hesitate to undertake pedigree breeding. This 

 project was, therefore, planned to determine whether it is possible to build up 

 and maintain desirable characters in a poultry flock without pedigreeing, but 

 through the annual introduction of males from superior stock.
