EGGS, SELLING BY WEIGHT.—There is a great 
difference in the size of eggs. There is a considerable 
difference in the eggs produced by different breeds. For 
example, the eggs of Hamburg hens are very much 
smaller than those of the Light Brahma or Langshan 
hens. As the composition of all eggs is very much the 
same it follows that eggs are valuable for food purposes 
exactly in proportion to their weight. In connection with 
some experiments the North Carolina Experiment Sta- 
tion recorded the weights per dozen as well as the num- 
ber laid by pens of several breeds for a period of six 
months. Asa rule the largest eggs were laid by mature 
hens, and the hens of a given breed laid larger eggs than 
the pullets of the same breed. The eggs laid by Pekin 
ducks, both old and young, were heavier than those of 
any breed of hens, weighing 35.6 ounces per dozen. Of 
all the breeds tested the largest eggs were laid by Light 
Brahma hens, weighing 28 ounces per dozen. The Black 
Langshan and Barred Plymouth Rock hens’ eggs weighed 
a little more than 26 ounces per dozen, while those laid 
by Single Comb Brown Leghorn, late-hatched Plymouth 
Rock, White Wyandotte and Buff Cochin hens, ranged 
from 21.7 to 23.7 ounces per dozen. The Black Minorca 
pullets laid the heaviest eggs of any of the breeds tested, 
their eggs weighing 26.5 ounces per dozen. The lightest 
eges were laid by Single Comb Brown Leghorn and Sil- 
ver Wyandotte pullets, their eggs weighing 17.5 and 22.1 
ounces per dozen respectively. Barred Plymouth Rock, 
White Plymouth Rock, White Wyandotte, Black Lang- 
shan-and Buff Cochin pullets’ eggs all weighed not far 
from 24 ounces per dozen.
