Lippincott: A Hen Which Changed Color 
LEFT SIDE VIEW TAKEN SAME TIME AS THOSE ON OPPOSITE PAGE 
The photographs on this and the opposite page were taken August 7, 1918, eight months later 
than the photograph reproduced in Fig. 1. 
Six weeks after the above condition obtained, all 
the feathers had changed to snowy white, a condition which the hen has retained to the present 
time. See Fig. 7. (Fig. 4.) 
University of Wisconsin flock. But five 
chicks here hatched, of which one was 
blue-splashed and four were blue, the 
theoretical expectation being 1.25 
splashed, 2.50 blue and 1.25 black. 
The following year, 1918, while in 
the condition, as regards color, shown 
in Figure 1, she was mated with white 
Wyandotte #118M from the Kansas 
State Agricultural College flock. As 
shown in an unpublished paper the gen- , 
etic constitution of 118M was pp(rE) 
(rE), so far as the factors under con-:: 
sideration are concerned. The expec- 
tation from such a mating would be 
equal numbers of blues and_ blacks. 
Twenty eight chicks were hatched, of, 
which thirteen were blue and fifteen 
were black. 
The next breeding season, 1919, after 
C2032 had become. pure white, she was 
mated to a white Plymouth Rock #155 
M (see Fig. 5). Twenty five chicks 
were hatched, of which seven were blue 
and eighteen were black, the theoreti- 
cal expectation being 12.5 for each 
color. This deviation is probably not 
is : Dev. 
significant since a= =3.2. A black 
and a blue chick, offspring of this mat- 
ing, are shown in Figure 6.
