PRAIRIE FARMER'S POULTRY BOOK 



A study of the chart will explain how these characters can be 

 maintained without loss. 



Cautions 



If brother and sister are mated they should be of pro- 

 nounced vigor, vitality and prepotency. 



If the first inating in line-breeding produces inferior stock, 

 the mating should be abandoned and a new one tried. 



If. occasionally a sport is thrown, the breeder should not 

 be discouraged. By selecting the best each year this tendency 

 will be overcome. 



If new blood is to be introduced into a strain it will be 

 safer to do it through one or two choice females than through 

 a male. 



If the original sire and dam are not closely related, there 

 need be no close inbreeding. If they are closely related, how 

 can two bloodlines be made out of one?
