in the strong flocks 

 was therefore sHghtly 

 less — 8 mills per 

 dozen eggs — than in 

 the weak flocks. 



As shown in the 

 financial statement, 

 Table 38, the strong 

 flocks produced 

 enough more eggs 

 than the weak to total 

 2 1 cents more per hen. 

 Considering the value 

 of the gain in weight, 

 the cost of stock that 

 died, and the cost of food, there remained a difference between the average 

 strong and weak flocks of 14 cents per hen in favor of the strong flocks. 

 Although the number of hens in the strong and weak flocks was the same 

 at the start, the true total number* throughout the experiments was 186.56

for the strong and 177.38 for the weak. The total difference between the 

 income from eggs and gain in weight, and the cost of food and lost stock, 

 therefore, is $287.30 for the strong fowls less $248.33 for the weak fowls, 

 or $38.97. These figures do not represent the actual balance profit, 

 since the labor, incidentals, and interest on capital invested are not in- 



* The true total number of hens is obtained by totaling the number of days each hen was in the ex- 

 periment and dividing the sum by the total number of hen days in a year.
