Changes in Egg Production 

 IN THE Station Flock 



By H. D. GOODALE AND RUBY SANBORN 



The egg production of a flock of Rhode Island Reds was 

 increased from an average of 114 eggs per bird annually in 

 1912-13 to 200 in the last year of record, 1920-21. This 

 represents an increase of seven dozen eggs per bird resulting 

 from the breeding methods followed. The pullets in the 

 last flock commenced laying much younger than those in 

 the earlier flocks, there being a difference of 55 days in age 

 at first egg between the two extremes of record. The winter 

 production per bird increased from 28 eggs in the earlier 

 flock to 67 eggs in the last flock. This bulletin describes 

 the breeding methods through which these marked changes 

 in the egg-producing efficiency of the Rhode Island Red 

 flock were secured.
