PROFITABLE POULTRY PRODUCTION 



The pullets from group 4, when mated to the cock 

 in group i, would give progeny in group 6, the 

 chicks in which would be seven-eighths the blood of 

 the sire, or practically pure bred so far as utility 

 requirements go. 



The chart is extended to show how other com- 

 binations occur. In group 9, produced by crossing 

 a cockerel from group 6 with pullets in group 7, and 

 also in group 13 produced by crossing a cockerel 

 with pullets in group 10, the result is half breeds 

 as in group 3. Group 5 results from crossing a 

 cockerel in group 3 with the hen in group 2. The

progeny in that case would be seven-eighths of the 

 blood of the mother instead of the father as in group 

 6. In group lo, the chicks result from a cross of a 

 cockerel from group 5 with pullets in group 7. The 

 reverse of this is the case in group 8. Groups 11, 

 12, 14 and 15 explain themselves. 



Should it be thought desirable to introduce a new 

 line of blood, it is best to do this through a pullet 

 or a hen mated to a cockerel as shown in group 8. 

 The reason for selecting a female is that it is safer
