    is it true that if I cross a splash blue laced red dottie with a salmon favorelle hen that all the males will be buff and the hens will be blr?

    and what if I crossed the same blr splash roo with a welsummer hen, I read all the chicks will be blr. is this true?

    The first mating (gold male X Silver female) will give gold pullets & split silver/gold males. You will probably lose all lacing or any showing will be of very poor quality.
    The second mating will give all Blue Duckwings,(Blue Breasted Red) same comment on lacing

    Quote:you lost me, my blr is a male and my fav is a hen (is this the gold male and silver female?- who's silver?)
    sorry to be so dumb, usually I can get this genetics but chickens are so complicated!
    anyone have a picture of a blue duckwing?

    It is the genetic makeup of each variety.

    Every male chicken has 2 genes at the S-locus. Each of these may be the S allele (silver) or the s allele (gold). Becuase this gene is sex-linked, females have only one copy, but once again it is either S or s.

    Thus males can be either SS, Ss or ss and females are either S or s.

    In your case, blue laced red includes at least the following geneset:
    e^b e^b, Co Co, Mh Mh, Bl bl, Pg Pg, Ml Ml, s s

    and salmon includes:
    E^Wh E^Wh, co co, Mh Mh, bl bl, pg pg, ml ml, S

    From this mating, all offspring will all receive:
    E^Wh e^b, Co co, Mh Mh, Pg Pg, Ml ml

    Additionally, half will receive Bl bl and the other half will receive bl bl

    Sons will receive S s and daughters will receive s.

    Quote:ok tell me if I am right, BLbl is blue and blbl is splash, BLBL would be black? but what would S look like or s look like?

    You have black (bl bl) & splash (Bl Bl) backwards.

    All the genes add up and work together. Chickens have only two pigments that form all the various colours in their plumage: red and black. The various genes present in a bird determine how each of these two pigments is or is not distributed to to the feathers.

    The various colour genes either act to intensify or dilute the pigment, or they affect the locations where it is distributed: either extending the pigment to additional areas of the body or restricting it from being placed in certain areas. The various genes that affect patterns on individual feathers (secondary patterns) work in a similar manner.

    The genes that enhance or dilute pigment may work on both pigments, or only on one of the two.

    Blue dilutes black pigment with little affect on red.

    Silver dilutes red pigment with no affect on black.

    Mahogany enhance red pigment, turning gold to red.

    Silver dilutes the mahogany to a salmon colour.

    Quote:according to feathersite,under breeding blue wyandottes
    I am right but it's not bl it's bb no l in the genotype for blue/black/splash.

    Black = BB
    Splash = bb
    Blue = Bb

    B is the designation for the barring gene, not the blue gene.

    Blue is designated with the symbol Bl. One copy of blue is designated Blbl and has the phenotype of blue. Two copies of blue is designated BlBl and has the phenotype of splash. Zero copies of blue is designated blbl and has the phenotype of black.

    If feathersite says otherwise, it is incorrect. Please check any chicken genetics website or book. This gene is probably more well documented than any other.
