The following table gives the total number of eggs produced 

 in all of the pens containing the same number of hens, and the 

 average yield of eggs per bird. 



EGG YIELDS WHEN ALL PENS CONTAINING THE SAME 

 NUMBER OF BIRDS ARE COMBINED. 



45 *birds, 15 in each pen gave 2,929 eggs. Per bird, 65.1. 



80 birds, 20 in each pen gave 4,830 eggs. Per bird, 60.4. 



100 birds, 25 in each pen gave 5,136 eggs. Per bird, 51.4. 



90 birds, 30 in each pen gave 3,612 eggs. Per bird, 40.1. 



The table which folloAvs shows the most profitable number of 

 hens in a flock in these experiments. 



= The April hatched birds in Pen 1 not included in this table.
