Poultry Breeds (Layer
Form)
A variety of poultry breeds are there
and based on the efficiency of
production specific breeds are used
to serve specific goals, which
includes
Layer form,
Broiler
Dual Purposes
Bovans Browns,
White leghorn,
Two of the most widely
cultivated for the purpose of
Layering because of their high
production rate.
Bovans Brown
The BOVANS BROWN is a layer
form poultry breed, brown
feathered, brown egg layer which
has the ability to meet the
expectations of a variety of egg
producers with different objectives..
She not only performs well for the
egg producer with traditional
production facilities, being very
docile is making her the perfect bird
for alternative production methods
as well
She is the bird of choice for today's
egg farmers who expects high egg
numbers and a forgiving bird, all
essential ingredients to keep their
business profitable.
Egg quality can deteriorate faster
later on in life than layers that
produce smaller numbers of eggs if
they are pushed too hard in their
early years.
In general, these birds will produce
a large number of eggs during their
first 3 to 4 years, even up to 330
eggs in their first year.
Our eggs are collected at least
twice a day. They are immediately
placed in the refrigerator.
SHELF LIFE
Eggs that are handled properly and
stored in a refrigerator at 45 F will
last 4 weeks.
CLEANING
Egg shells are very porous when
wet. We do not wash our eggs
because you can force bacteria into
the egg itself. The accepted method
of “cleaning” an egg that has been
soiled is to use abrasion
(sandpaper) to remove any material
on the egg shell. That is why you
might find some areas where the
shell appears scuffed.

changed to Leghorn from the Italian
port that they were first transported
through.
Appearance

Have white feathers that are very
bright and beautiful.

Eyes: Red-Orange
Weight:
Male: 2.4–2.7 kg Female:
2.0–2.3 kg
Purpose
White leghorns, due to a smaller
body are for Egg-Laying purposes.
Due to their prolific egg-laying, they
are the number one breed used for
large-scale commercial egg
production

Life span
The white leghorn chicken has a life
expectancy of 1 to 6 years.
Those living in factory settings tend
to have slightly lower life spans.
Egg production
Eggs a week/year: 5-6 eggs a
week/280-300 a year.
However, production does decrease
over time, and will stop completely
during molting.
When the hen is about two or three
years old, production decreases by
10 to 20 percent.
Leghorns also need 14 to 16 hours
of light each day in order to stay in
high production.
Egg laying slows in winter because
of fewer daylight hours, unless you
provide additional lighting in the
henhouse.
