THE BIIEEDING OF CHICKENS 129 



gi\'cii as 17iM207 because tlie sire is 17M and the clam is 207, 

 this information having been transferred to the Flock 15reed- 

 ing iiecord from a sheet of the Chick and Mating Index not 

 shown in the accompanying figures. If the numbers ran 

 higher and it was found tliat the mating number of 10,012 

 was 115M200(1 (Figure 01 lower left hand corner) the fact 

 would be clear that the sire of 10,012 was 115M and the dam 

 was 2006. 



The Flock Breeding Record bears the same relation to the 

 flock of the individual breeder that the herdbook does to an 

 entire breed of cattle. It enables the breeder to readily trace 

 the ancestry of any individual in his flock back to the parents 

 of the individuals with which the record was first started. 



Thus, whenit has been found that the sire of 10,012 is 11.5^1 

 and that the dam is 2000, it may be easily determined by 

 looking u]) 115AI in the Flock Breeding Iiecord (Figure 62) 

 that its sire and dam are 85M and .519 respectively. In 

 the same way it may be disco^'ered that the parents of 2006 

 are 85M and 505. She is therefore a half sister of her mate. 

 The further ancestry may be traced back to the first birds 

 recorded as shown in Figure 63. 



When individual egg records (see Figure 64) are kejJt for 

 all females used as Ijreeders the nuiting members of the 

 females may be written on the egg record sheets. When 

 this is done it will be nesessary to keep a flock breeding 

 record for the males only. 



A pedigree blank as shown in Figure 6.3 is highly desirable 

 for assembling the information gained from the Flock Breed- 

 ing Record. Below the spaces intended for the female ances- 

 tors are spaces for the yearly egg records completed by each 

 one. 



Official Records. — As pre^'iously indicated (see page 57) 

 there are no official breeding records for poultry, though the 

 question of the registration of poultry is being agitated. The 

 production records made at the laying contests conducted by 

 several states are recognized as authentic and those records 

 of two hundred eggs or higher made at contests are recorded 

 as ofticial by the American Record of Performance Council. 

 This Council is authorized and organized by the American
