SUCCESS IN POULTRY CULTURE 
you have plenty of good breeding stock 
and plenty of eggs to select from, it is 
best to choose eggs with thick, strong 
shells for hatching. No breeder ever 
ought to be guilty of sending out thin, 
weak-shelled eggs to his customers, but 
they sometimes do it, and when we receive 
such eggs we have to get along the best 
we can with them. 
If you always select well-shaped eggs, 
with strong, thick shells, the tendency to 
produce such eggs will soon become in- 
herent in your flock. The tendency of 
your flock to produce eggs of a desired 
color can also be strengthened by careful 
selection of the desired color. By select- 
ing eggs with the desired shape and color, 
and strong shells, and from hens that are 
the strongest in the qualities that you 
desire to transmit and strengthen, and 
selecting your male birds from such hens, 
you will slowly but surely improve your 
flock. Don’t expect too much improve- 
ment from your selections, for the ten- 
dency in nature to deviate is so strong 
that disappointment follows the most 
skillful breeding.
