This table is arranged consecutively according to the year that the experiment was conducted. 
The averages of pens 7 to 16 are not included because deficient rations were fed in several of these pens, 
malving such averages of no value. 
Missing hens and those killed by hawks are included with the hens that died (last column of table) as 
follows: Second year, missing, one from Pen 1, two from Pen 2, one from Pen 4, and one from Pen 6; killed 
by hawks, one from Pen 4, and two from Pen 8; third year, missing or killed by hawks, two from Pen 4, 
three from Pen 8, two from Pen 9, one from Pen 10, four from Pen 15, and two from Pen 16. 
The cost of the green feed which was fed in the yarded pens (Nos. 3, 5, and 7) is not included in this table. 
It amounts to about 10 cents per hen, or 1 cent per dozen eggs (see p. 18). All costs throughout this bulletin 
are figured on the basis of feed only and do not include labor or any other items. 
The general-purpose breeds ate an average of about 70 pounds of 
both grain and mash per head in one year, while the Leghorns con- 
sumed about 55 pounds per head. On this basis, if their feed is regu-

Fig. 1. — Average egg yield and feed consumption per hen in Pen 8 for 
2 years by 4-week periods. (This necessitates repetition of month of 
May so as to make 13 periods in the year.) 
lated so that the hens will eat equal parts of scratch grains and of 
mash, 100 fowls of the general-purpose breeds should be fed about
