Eggs
(Part I)

Newly
discovered breeds, such as White Leghorns, looked promising
as layers. |
|
Three hundred eggs per bird is now the accepted commercial average,
yet at the beginning of last century the average commercial egg production
of the laying breeds was probably less than a hundred eggs per year.
Average egg production in the United States in 1909 was officially
recorded at only 83 eggs a bird. Yet it is recorded that some individual
birds lay up to 250 eggs, and that some newly discovered breeds such
as the White Leghorns were looking most promising as egg layers. At
that time there was an extreme variability in egg production of the
various birds and breeds.
Currently in Australia the average egg production on the top commercial
poultry farms is around 280 eggs per bird. In Europe and North America
the average is closer to 300 eggs per bird. I have had some of these
layers, from the European breeders, in my back garden, and they
laid their 300 eggs in their first year and continued to lay well
even in their second year. In Australia these European breeders
sell their parent and grandparent breeder stock to Australian hatcheries
under a franchise. My birds were an off spring of these, the same
birds that are sold to most commercial egg farms.
How these big improvements in egg laying came about initially was
through Governments encouragement to the poultry industry. At the
beginning of last century there was great interest in commercial
poultry breeding and in the setting up of thousands of small chick
hatcheries. The hatcheries sprung up everywhere because of the newly
invented incubators. There were many business opportunities to supply
the poultry farmer with chickens. This happened in North America,
in parts of Europe, Japan and in Australia and New Zealand. The
Governments of these countries encouraged the setting up of Government
breeding farms and egg laying competitions.

After this development in improving the average egg laying capacity
of some breeds in Europe and America, the Japanese Government started
importing breeding stock from Europe and America. As a result of
this importation of mainly White Leghorn stock, by the mid-1920's,
Japan was 'flooded' with thousands and thousands of commercially
useless While Leghorn cockerels. Hence the urgency, in Japan in
particular, to find some way of being able to distinguish the difference
between pullets and cockerels as soon as they were hatched and so
ovoid the waste of rearing these unwanted White leghorn cockerels.
This urgency to cut the waste was the main reason why commercial
chick sexing was developed and perfected in Japan.
Government's encouragement to poultry farming:
In Australia, the various State Governments were actively encouraging
farmers and small landowners into poultry and egg production. The
aim of the State Governments was to encourage and support the large-scale
export of dressed poultry and eggs to the then very lucrative London
market, during the English winter 'off season'. This export was
made possible by the development of refrigerated shipping by Thomas
Mort in Sydney in 1879. Export was organized through the newly established
Government cool stores in the capital cities.
The State Governments of Victoria and New South Wales were particularly
active in encouraging the poultry industry to develop. The First
Egg Laying Competitions were in Australia. The first egg laying
test were set up in NSW at Hawkesbury College in 1901, and at Dookie
College in Northern Victoria in 1904, and at Burnley Gardens (Burnley
an inner suburb of Melbourne) in Victoria in 1911.
Other countries such as Canada, the USA and England followed soon
after this. However the laying competitions in Australia at least,
produced some disappointments. Some winners with records of 200
eggs, or six or twelve bird teams with averages of up to 230 eggs
often produced mediocre breeders with disappointing results in their
female progeny. But despite this there was progress in raising the
commercial egg production in the early stages. Breeders improved
their techniques by using only breeders with outstanding pedigrees,
as one writer has put it, 'something akin to those used in breeding
of racehorses'. But it was realized that something more was needed.

Handling eggs mechanically and manually.

In the 1930's and 40's the United States Department of Agriculture
operated a large-scale poultry improvement scheme (the U.S. Record
of Performance) where over 150,000 pullets a year were tested on
hundred of co-operating breeding farms. Trap nests were use to record
which birds lay each day. This mass individual performance records
was used in a vast breeding program based on pedigree. But in spite
of all this effort the eggs per year were still low by today standards.
For example in the U.S. in 1942 it was 113 eggs per bird, by 1948
it rose to 162 eggs. In Australia the average in 1954 was only 144
eggs per bird. The big breakthrough was to come later. The breakthrough
came through the development in the U.S.A. through theoretical work
by mathematicians and the development of the 'population genetics'
approach to poultry breeding in the U.S. Other countries, including
Australia improved their laying flocks egg production, but no one
would argue the U.S. was far ahead of the rest of the world in their
egg laying breeding stock and later also in their broiler breeding
stock. In these two areas of poultry breeding they have dominated
the world.
Eggs and I
a lifetime together
When I experience the performance of my few back garden hens that
were bred from the decedents of these genetically bred stock, my
mind boggles to think how successful I would have been if I had
had such birds on my own commercial farm in the 1950's and 60's;
of course I would have needed to have had them when no other farmers
had them. My own flock average on my farm would have been about
150 eggs per bird, compared with my current 'back garden' flock
of 340 eggs per bird in their first year of lay: month after month
they laid at a 100 percent production. Had any one else told me
that their 'back garden' birds laid this well I would not have believed
them. Most of my 'back garden' hens kept on laying well into their
second year, but by then I was over the 'shock' of their performance
and no longer kept a record of their laying.
As this essay is about eggs for the table: I should record here
that I am a regular egg, eater for breakfast, from way back. As
a child from about four years up till I was about ten years old
I had an egg for my breakfast most mornings. Then from about 23
till I gave up poultry farming at forty I had two eggs for my breakfast
ever morning. And since I gave up secondary college teaching, about
nine year ago, and have again got 'back garden' chooks, I have two
eggs for breakfast six days a week.
My friend of over forty years Hartley Hall, a fellow former commercial
chick sexer and poultry farmer, also eats two eggs for breakfast
most mornings, and has done so for most of his life. When we went
to Japan several years ago to research my book 'The Specialist Chick
Sexer' it was my task to cook the breakfast each morning: Mr. Hartley
Hall was a very fussy man when it came to how his eggs should be
cooked. It is from Hartley that I got most of the news's cuttings
in Part II of 'Eggs' I have included them for your interest; you
can form your own opinions about the nutrional value of eggs. I
am not trying to sell you or advise you about eggs. Here I can only
write about my own relationship with the egg over a lifetime.
The egg or the chicken first
Eggs can be used for producing chickens, which of course are its
prime function; the old debate of whether the chicken or the egg
came first is easy answered. Neither came first.

When you look at a table, a home, a car or whatever remember they
all started as an idea in someone's mind, so it is with a chicken
or an egg. Egg producers, poultry fanciers or commercial poultry
breeders get the idea of what type of bird they wants to breed and
develop. The tremendous progress that has been achieved in poultry
breeding and the number of eggs a hen lays in a year, all started
off as an idea in someone's mind.
In Part II of the 'Egg' essay I will included some bits and pieces
about eggs, whether you are regular egg eaters like Hartley Hall
and me, or just a casual egg eater, I hope you will find some interest
in these newspaper extracts of Part II.
Good luck
