BREEDING
OF THE BLUE VARIETY
WITH EMPHASIS ON THE THE LACED BLUE VARIETY

By David Plant October© 2001

The
following notes have been extracted from my experiences over the
past 35 years in Breeding the following Blue Varieties, Old English
Bantams, Pekins & more recently establishing a new gene pool
of Laced Blue Langshan Bantams derived from Black Langshan x Blue
Orpington
In
this article I will endeavor to give the reader an insight into
breeding Blues and how the Blue Laced variety is pivotal to the
success of a Blue Pekin Line and how to sustain that colour
The
breeding of the Blue and laced blue Pekin variety of bantam in Australia
must be viewed in the context of Mendels theory as applied to the
Blue Andalusian Fowl which is as follows:
Bateson & Punnet (1906) demonstrated that the Blue Andalusian
fowl when mated together segregated into progeny of three colours,
Blue laced, Black and Splashed white. Blue laced, the colour required
for exhibition was shown to be the result of the impurity of a gene,
Bl being present.
In
R.C. Punnets book on Mendelism he explains that when the three various
combinations of Blue plus Blue cross matings are made, the following
results in colour distribution can be expected:
|
Blue |
Black |
Splash |
Blue |
50%
Blue, 25% Splash, 25% Black |

Because the following popular Blue varieties today have the same
genetic make-up as the Andalusian they utilise the above principles
of expected colour distribution. Among those breeds are the Blue
Old English, Pekins , Leghorns, Orpingtons and Blue Laced Wyandottes
as well as several other popular blue breeds. Mendels Theory and
Punnets explanations are said to apply.
The
description of the Blue Andalusion dictates colouring as follows:
"Clear
Blue edged with distinct black lacing, not too narrow, on each feather,
excepting the males sickles which are dark or even black and his
hackles which are black with a rich gloss, whilst the female's neck
hackle is rich lustrous black showing broad lacing on the tips of
the feathers at the base of the neck. Undercolour is to tone with
the surface colour."
The
actual lacing on popular varieties in Australia tends more to be
Dark Navy Blue where depicted as "black "in the Andalusian.
Dark navy also relates to Neck hackles, back, tail coverts and sickles
in the males and neck hackles in the females. My belief is that
even in written descriptions of the Andalusian the colour was not
Black but the very darkest of Blue.If it were a two-tone Black and
Blue bird then the Mendels Theory of colour distribution would hardly
apply
BLUE LACED OR UNLACED BLUE IS NOT A COLOUR THAT BREEDS TRUE
Many
breeders when starting out often think that by mating two blues
together that they will produce offspring all of a blue colour.The
reason this does not occur is that the only ones produced from the
mating of blue to blue, that breed true when mated together are
splashed white and the black. In other words black mated to black
will produce all black and splashed white mated to splashed white
will produce all splashed white.
In fact the Blues that are produced from these matings will more
often than not be a mixture of different shades of Blue.
"SELF
BLUE" IS THE ONLY COLOUR THAT BREEDS TRUE TO BLUE
The
Definition:
Self-blue is a shade of uniform Pale Blue throughout without edging
to any of the feathers. The most distinct aspect of birds possessing
this genetic colour makeup is that when they are mated together
they will only ever produce 100% Blue offspring of a similar colour.
In any of the popular breeds mentioned herein it is incorrect to
call any of them "self -Blue"There is no self- blue gene
that has been developed in Australia at the time of writing.
The only self blue fowls presently in Australia is the Araucana
and the Belgian Bantam none of which were originally developed in
Australia themselves
Over many years people are still incorrectly calling pale Blue unlaced
birds"self Blues".
The
Standard
Because the Pekin standard in Australia allows the exhibiting of
both the laced and the unlaced varieties Nature dictates that there
are two pens of birds used in the breeding pens to produce the blue
colour shades required to comply with the Standard
In terms of the laced Blue Pekin this colour descriptions used to
describe a cockerel breeding line and the unlaced version is used
to describe a pullet breeding line in some varieties. The un-laced
version is usually of a lighter shade of blue due to the lack of
Navy pigment in the female used., containing no navy edging to each
feather. The females in particular are often described as “powder
Blue” because of their soft all over light blue colour
Much
confusion and poor results often occur when breeders mix the two
lines and expect the laced variety to result from a cross between
the two colours. Some lacing may occur but the cross reduces the
effects of the lacing by 50% so partial or incomplete lacing is
often seen on progeny from these matings and detracts from the birds
overall appearance (i.e.by crossing laced with non-laced)
|
Excellent
type is neither fully laced or unlaced but more over described
as even blue throughout |
THE LACED
GENE
For readers to fully appreciate the laced Blue Pekin they must firstly
realise that the lacing produced on the feathers of the Pekin has
arrived there because of a set of factors that have combined to
produce the fine dark edged lacing around each feather. These are
called genes and it is the genetic make-up of the parents of the
bird that dictate whether the bird will be laced or not. In other
words it is an inheritable feature carried from the parent stock
and without the lacing gene, laced feathers will not miraculously
appear.
It
is virtually impossible to breed a correctly laced bird from parents
that do not visibly exhibit the lacing factor, unless one or both
of the parents have had the lacing gene in their background. Meaning
that one or both of their parents may have the lacing component
and the offspring have not exhibited the trait. One would need to
be fully aware of the parentage of the birds being used in matings
to be able to predict any sort of accurate result.
Birds that do not have a visible laced feather but are known to
have had laced parentage will carry a diluted form oflacing.
Breeding back to another bird with sound lacing will assist in producing
lacing although it may take two generations of mating back to achieve
the results required.
From
my experiments in crossing Blue Laced Orpingtons and Black Langshan
Bantams I have found that the Blue Laced Orpington has an extremely
strong inheritable set of laced genes that has now carried on for
6 breeding seasons to still produce a rich blue ground colour complemented
by fine dark edging in the Blue Langshan offspring.
