How stocking density affects
free-range hen behavior

kept on the range.
MARK CLEMENTS

Stocking densities may affect range
use as well as where and for how long
free-range hens rest.

There is no universal standard for the outdoor stocking
density of free-range laying
hens, and different certification
bodies have their own requirements.
These requirements are not
always based on strong evidence,
meaning that not all current
stocking density recommendations applied around the world
will necessarily result in the best
returns for egg producers nor the
best welfare for hens.
Ongoing studies in Australia,
however, which have recorded

perimental farms and is yet to be
applied to commercial premises.

several indicators of how laying
hens are affected by different
stocking densities, may help to
solve this problem.
The work was carried out
as part of the Poultry CRC's
"Outdoor stocking density in
free-range laying hens: Effects
on welfare" research project.
However, it's important to note
that it was conducted only on ex-

Bird behavior was measured
in stocking densities of 2,000,
10,000 and 20,000 hens per
hectare (hens/ha) to determine
whether certain behaviors used
as welfare indicators were influenced by the number of birds on
the range.
Observations of hens indoors
and outdoors showed that when
hens were provided the choice,
they preferred to dust bathe and
forage outdoors but rest indoors,
and the frequencies with which
they exhibited these behaviors
were affected by stocking densities to varying degrees.
Hens from the lowest stocking densities used the range the
most, while those in the highestdensity flocks used it the least.
With more hens going out-
