FOREWORD TO SECOND EDITION 



The fact that a new edition has been made necessary in 

 so short a time is a gratifying sign that this book has filled 

 a need. In this second edition the book has been revised 

 and partially rewritten to bring it down to date, for poultry 

 work is constantly progressing.
