The Case Of The
Chicken Chicken
■Who's who In the “peck
ing order” preoccupies lay
ing hens so much that poultry
■dentists try hard to under
stand this aspect of social
life in the henhouse. For ex
ample, previous evidence in
dicates that a hen’s egg pro
duction and length of life re
late to how aggressively she
pecks.
Recently, poultry special

toward another to . clarify
these specific points:
1 Do chicken strains
vary in aggresstvehess?- >And
does relative aggressiveness
of a chicken strain change
over a period of time?
2 Is aggressiveness re
lated to size? Do birds rec
ognize superiors as Individu
als or as belonging to a
superior strain?
3 Is aggressiveness link
ed to egg quantity or qual
ity? -
Relationships between
strains were given special
consideration in planning the
study.

nek and L. D. Tlndell, both
formerly of the Georgia Ag
ricultural Experiment Station,
studied pairs of hens in a
special observation cage. They
matched birds from four
strains of White Leghorns and
two strains of Rhode Island
Reds, in three encounters.
Although the tests took on
some aspects of a tourna
ment, none of the birds was
injured.
The first pairings were
held when the birds were 20
weeks old, the second and
third at 38 and 56 weeks. *

other hen simply withdrew
when she threatened. As soon
as the researchers could Judge
which hen dominated the oth
er, they returned the birds
to individual cages.
The experiment clearly es
tablished that there are su
per strains in the chicken
world. Each stock revealed
a clear level of aggressive
ness, which the scientists be
lieve is earned genetically.
In general, the relative ag
gressiveness of a strain did
not change with age Only
in the last .rematch did the
two least aggressive strains
exchange standings.
