The Leghorns on free range gave a considerably greater egg yield 
than those confined to a fair-sized yard. This difference was less 
marked in the general-purpose hens. 
Sprouted oats fed as green feed to hens confined to yards cost 
about 10 cents per hen a year and 1 cent per dozen eggs, not including 
any charges for labor and equipment. The hens ate on an averag 
in one year about 1.3 pounds of oyster shell and 0.7 of a pound o: 
grit, which together cost about 1 cent per hen. 
The Leghorns did not lay as well in the winter as the general- 
purpose breeds, especially during their second year, but the Leghorns 
produced eggs about 3 cents per dozen cheaper during their first year, 
6.4 cents cheaper in their second year, and 9.8 cents cheaper in their 
third year than the general-purpose breeds. One pen of Leghorn ; 
pullets (Pen 8) produced eggs in their first year at a feed cost of 6.7 
cents per dozen, while the value of the eggs per hen for the year was : 
S3. 41 over cost of feed. 
The average weight of a dozen eggs from the general-purpose fowls 
during their pullet year was 1.53 pounds, 1.60 during their second 
year, and 1.63 during their third laying year. The eggs from the 
Leghorns averaged 1.45 pounds during their pullet year, and 1.49 
during their second and third years. 
The egg production of the general-purpose fowls decreased 32 per 
cent in their second laying year. The decrease was considerably 
less in the Leghorns, their 2-year average egg production exceeding 
that of the general-purpose breeds by 19 eggs. The decrease in pro- 
duction from the second to the third year was only 4 per cent with • 
the Leghorns, compared with 13 per cent in the general-purpose 
breeds. 
The cheapest eggs are produced in the spring, during April, May, fc 
and June, while the greatest costs occur in October, November, and 
December. The lowest monthly feed cost of a dozen eggs in an}- of 
these experiments was 4 cents, while in some cases no eggs at all 
were produced during the month.
