flock — the weak Barred Ph'mouth Rock flock, the exception throughout 

 all these tables. Even with this exception, the average of all strong 

 flocks shows a mortality several per cent lower than that of the weak 

 flocks. 



INCUBATION 



The two-year results in incubation given in Table 36 show a consistent 

 and decided superiority of the strong over the weak flocks in each of the 

 comparisons, as well as in the averages of the strong and weak flocks. 

 The average fertility of the eggs from the strong flocks was 7.5 per cent 

 greater, and the hatching power of the eggs 7.6 per cent greater, than 

 from the weak flocks. The chicks from the strong pens were also heavier.
