eggs. Eleven flocks averaged between 140 and 150; five between 130 

 and 140, and four between 110 and 130 eggs. 



The pullets in all 23 flocks produced approximately 150 eggs per 

 bird, or 41%. Only one flock was below 130 eggs. Four were between 

 130 and 140, eight were between 140 and 150, and ten were over 150 

 eggs. 



The production of old hen flocks, which made up about 12% of the 

 total number of layers, was considerably lower than that of the pullets, 

 being only 112 eggs, or 31%- per bird. This is 38 eggs less than the 

 average pullet production. 



Toward the end of the year, there were a few pens of early hatched 

 pullets housed. The production of these 1930 pullets averaged 20.8% 

 for the short time before the records were closed, and is included al- 

 though the period was so short that there was little effect on the flock 

 production for the year. 



Egg Production by Weeks 



Figure 8 indicates the average percentage production by weeks for 

 pullets, old hens and the flock as a whole on the 23 farms. Flock pro- 

 duction was high from the last week in February to the first of June 

 with a peak in the week beginning March 30; the low per cent produc-
