    I was just curious first of all what the "self" means in self blue. What could I reasonably expect if I were to cross the the two types of blues ?

    Self Blue is also referred to as Lavender. It is a recessive gene/color that is on a completely different locus from Blue, also known as Andalusian Blue from its originating breed. Blue is dominant, but does not breed true, as homozygous (both copies) makes a "splash"

    So does self blue breed true ? Also, I was told by the guy that sold me my black trio that I could cross blue and black and get about 50% each. Both my black hens are show quality and I'd really like to use one to improve my blues.

    Yes, self blue does breed true.

    Quote:Self refers to a color that is solid and evenly distributed over the birds entire plumage and does not have any secondary color patterns ( like lacing) associated with the plumage color.

    As Illia stated, self blues are actually lavender which is an expression due to a pair of recessive genes. The two genes dilute a black bird to light gray or blue color. The color is even and covers the entire bird.

    Blue is expressed by an incompletely dominant gene. One blue gene produces a blue bird - two blue genes produces a splash bird. Splash is a whitish bird that has splashes of black or blue feathering.

    Blue birds on the other hand have black lacing or feather edging associated with the plumage pattern; the head of the female is a darker color (dark blue to black) than the body and in males the pyle region is dark blue or black in color.



    Crossing a blue with a lavender will be like crossing a blue with a black. You will get the same results because the lavender is recessive.

    Blue X lavender = blue birds and black birds The blue birds may or may not have lacing or edging it depends genetics of the lavender bird and the blue bird.

    Quote:Yes, Blue and black yield 50% blue and 50% black.

    Blue on blue yields 50% blue, 25% black, 25% splash.

    Slash and black, 100% blue.

    Thanks so much everyone for the info !!! I have so much to learn since I'm new at this. I dealt with horses (breeding, training, and showing) for over 20 years, but quit about 7 years ago due to too many broken bones from young horses, plus the economy had about caused the horse market to crash. I like the fact I can get more than one baby and not have to wait a year for another one. Another question...is there a book or books that I can buy that can help me learn the genetics of breeding. I'd like one that deals with OEGB and also not just color, but type too. If there isn't, maybe one of you knowledgable people needs to write one. [​IMG]

    A blue (Bl/bl+) chicken crossed to a blue (Bl/bl+) chicken will produce blue, black and splash offspring, whether they are self blue (aka non-laced blue or solid blue) or blue (aka laced blue). Self blue and blue start out the same genetically (Bl/bl+). When Melanotic (Ml) and Pattern Gene (Pg) are added a self blue becomes a laced blue (aka blue or Andalusian blue).
    Lavender is not the same as self blue, as the APA/ABA claims, and can be confusing when fanciers use the terms interchangeable. Although the blue and lavender look like similar colors they are totally different genetically. Lavender (lav/lav) crossed to lavender (lav/lav) breeds true, producing lavender chicks.
