Organic Poultry Production: A Good Fit for Your Farm?
By
Tracy Salisbury and Brenda Frick
Organic poultry production offers opportunities to a range
of producers. It can complement an existing grain or livestock operation,
provide
a low capital cost start-up, short-term option for those new to livestock
production, or provide larger-scale possibilities to those transitioning
conventional poultry operations to certified organic production.
One
of the principles of raising organic livestock is that the animals
need to be able to express their natural behaviour. Natural behaviours
of poultry include pecking, scratching, and foraging for feed. Birds
run, stretch their wings, fly short distances, sun themselves and
dust
bathe.
Negative behaviours, such as feather pulling and cannibalism
are stress related. By providing good nutrition, adequate floor and
nest space,
appropriate lighting and by providing roosts much stress-related
behaviour can be avoided. Research shows that when over 66 percent
of the birds
in a poultry operation are actively using an outdoor run the incidence
of severe feather pecking disappears.
Some producers using a large-scale
commercial model of production rely on common commercial breeds. These
birds are bred for very rapid
early weight gain, and this can cause problems. It is usually necessary
to limit feed in the first few weeks to allow body structure to keep
pace with weight gains, otherwise birds may be crippled. Smaller ‘backyard’ producers
commonly use hybrids (e.g. Cornish Cross) or specialize in rare or
heritage breeds that utilize pasture better and are more mobile and
hardier.
Here on the prairies, we are lucky to have ready access to
affordable organic feed grains: wheat, peas, barley, oats, flax,
hemp, alfalfa
and screenings. Usually rations are supplied according to three stages:
starter, grower, and layer rations reflect decreasing protein requirements.
An organic pre-mixed complete ration assures the producer of a balanced
diet, and is great for producers without a land base to grow their
own grains, but it may be costly and hard to get. Another option
is to purchase organic concentrate (vitamin, mineral and/or protein)
and
mill it with available grains. Poultry do best with a combination
of seeds and grains, insects and forages. Grit (sand and gravel) helps
digest whole grains.
Poultry housing takes many different forms. Whatever
the type of housing used, it is important to encourage optimal health
and natural behaviors,
provide outdoor access, shade, shelter, rotational pasture, exercise
areas, fresh air and natural daylight according to the stage of production,
climate and environment.
Mobile units should be moved regularly or
pastures rotated frequently to maintain pasture quality and minimize
the buildup of parasites and
disease. Housing should also protect birds from predators and shelter
them from wind, rain and sun. Incorporating trees or constructed shelters
into the outdoor area and surrounding the pasture with appropriate
fencing will help. Sometimes electric fencing around the perimeter
of the chicken’s area and /or guard animals may be required to
provide adequate protection from predators. Electric netting may be
used as well as or instead of the above methods. Portable units must
be heavy enough that they do not blow away yet light enough to move
easily.
In a barn situation, it is necessary to rotate several runs.
This way, vegetation can recover in other runs while one run is foraged.
This
will minimize build-up of disease, parasites and manure. Providing
birds with outdoor access at an early age, at least by 3-4 weeks
old, will help to produce adults with a greater tendency to explore
widely.
This will assure that the available runs are used more efficiently.
Birds
spend most of their time during the winter in a poultry barn. Nesting
boxes should be dark so as to dissuade flock mates from pestering
a laying hen and to give her a feeling of security. Good quality
and adequate bedding is important to absorb moisture and encourage
scratching.
Straw and wood shavings are the norm. Adding layers of litter regularly
over the winter prevents volatilization of ammonia and provides a
source of heat as the lower layers compost. Good sanitation and regular
cleaning
of the housing unit is important to prevent disease, parasites and
pests.
There are many ways to make a poultry enterprise successful.
Prevention is the key to good health. Quality feed, clean water,
adequate shelter,
outdoor access to clean ground uncontaminated by excessive manure,
use of suitable breeds and diligent observation by the producer all
contribute to flock health. Good management can prevent most problems.
