4 cage-free house
issues producers
may not have
considered
Industry researchers use the
USPOULTRY Live Production,
Welfare & Biosecurity seminar to
discuss cage-free laying house issues
that may not have been previously
discussed by producers.

T

he future of cage-free egg production has been
a regular topic of discussion among the egg
industry for some time now. Challenges like
cost, health, pest control and conversion of housing are
just a few of the many concerns.
Darrin Karcher, poultry specialist, Purdue
University Department of Animal Sciences, and
Amy C. Murillo, University of California Riverside
Chancellor's Postdoctoral Fellow at the Department of
Entomology, used the U.S. Poultry & Egg Association
(USPOULTRY) Live Production, Welfare &
Biosecurity Seminar in Nashville, Tennessee, held on
September 17, to discuss potential issues to cage-free
layer housing that producers may not have faced yet.

Those include:

1. Toe pecking - Toe pecking is a huge issue in
Europe that Karcher witnessed firsthand during
his travels in Switzerland this summer. "They are
having major toe pecking issues and it is not genetic
driven or housing-system driven, so they are really

struggling to figure out what is causing these laying
hens to start toe pecking," he said. He explained
that he walked into one housing system where all
the hens' toes were full of blood from pecking. "I
haven't seen it here (the U.S.) yet, but it is something
they're experiencing, which likely means we will at
some point as well," he said.
2. Red mites - While the northern fowl mite is a
common parasite in U.S. poultry operations, the
poultry red mite offers some different issues and
may become more apparent in alternative housing
systems, Murillo explained. Red mites are already
a huge problem in Europe. Unlike the northern fowl
mite, poultry red mites live in cracks and crevices
and only come out about one hour a night to feed
off the host. Both types of mites live off the blood
of the poultry that they bite. Poultry red mites leave
the host every day and can survive many weeks of
starvation hiding in a housing system. Both types
of mites are hard to control and need various forms
of pest control options. An epidemiological review
