The creation of the Lavender Silver Laced Orpington bantam has been one of the most challenging breeding projects I have undertaken. From originally deciding to start the breeding process in 2012 it has taken four years to finally produce both pullets and cockerels with an established crystal clear lacing.   

2012

The original cross to create the Lavender Silver Laced Orpington was a Silver Laced Orpington bantam cockerel over a Lavender Orpington bantam hen. This created Black Orpington bantams that were split for Lavender and carrying the Silver gene.

By crossing the Black Orpington bantams produced from the original cross this produced a percentage of Lavender Orpingtons carrying the Silver gene. The expression of Silver throughout the plumage was quite random but the mix of both the lavender and silver on the same bird produced a stunning visual effect.

2014

I now wanted to clarify the lacing in the plumage so this required another cross back with a Silver Laced cockerel over my 2013 bred Lavender silver pullets. Out of this mating I bred good quality Silver Laced Orpington bantams that were split for lavender.

The cross from 2014 has now produced a percentage of Lavender Silver Laced Orpington bantams as well as good quality Silver Laced Orpington bantams split for Lavender.

2016

The Lavender Silver Laced Orpington bantams are now breeding true and producing the most beautiful delicate Lavender lacing on a clear Silver base. By being able to cross back into Silver Laced orpingtons at intervals it will be easy to introduce new blood into this colour to avoid inbreeding.

THE SILVER IN THE LAVENDER SILVER IS A SEX LINKED DOMINANT GENE

In poultry the sex of any chick is determined by the hen not the cockerel. The cockerel carries two Z chromosomes so he is ZZ. The hen carries one Z chromosome and one W chromosome so she is ZW.The cockerel must pass one of his Z chromosomes  onto his offspring so any sex linked genes that are on that chromosome such as Silver, Bantam, Barring and Chocolate will be inherited. The hen can pass either her Z or her W chromosome on to her offspring. If she passes her Z chromosome on her chicks will be male and they will inherit all the sex linked genes that are on that Z   chromosome but if she passes her W chromosome on,  her chicks will be female and they will inherit none of the sex linked genes she is carrying. Genes that are sex linked can only be carried on the male chromosome.

The Lavender Gene ( Pearl Grey )

Lavender is an autosomal  gene which means that as it is not sex linked it is inherited the same way on both male and female birds.

It is also recessive so both parents need to carry the Lavender gene for the young stock to visually show Lavender so a bird with only one Lavender gene will not show any Lavender colouring but can be used to breed Lavender.

Lavender breeds true so in its pure form Lavender mated to Lavender will always breed Lavender.

Lavender can also be used to create lots of new shades and colours as it is a diluting gene as long as the bird is carrying two doses of Lavender . All black colouring will become Lavender and any red pigment will dilute to a straw colour.
