A study of Table 28 

 and Fig. 165 shows that 

 the heavy consump- 

 tion of food in these 

 pullet pens occurred 

 during the periods of 

 heaviest weight of the 

 fowls and slightly pre- |||| 

 ceded the highest pro- 

 duction of eggs. These 

 figures confirm the data 

 given in Table 6 and 

 Fig. 163, Part I, and 

 in Table 17 and Fig. 

 164, Part II, of this 

 bulletin. * 



weight of eggs 

 In all comparison 

 flocks the average 

 weight of the eggs from 

 the strong fowls was the 

 greater . 1 1 i s noticeabl e 

 in Table 29 that there 

 were fluctuations from 

 period to period, and
