    the males have the buff gene right? I have a new duckling from one of my different drakes than the others and it looks like the others but it is alot lighter cream and light coco unlike the others that are black and sandy brown

    Ok, not quite sure what your meaning by "sex-linked grey ducks" do you mean Mallards? Restricted Mallards? Grey Call ducks? Grey Runners? etc.

    Unless you have some mixes in earlier generations the Rouen ducklings should all be similar in color. and unless i'm missing something they don't carry the buff gene, they are wild type.

    Lets look @ a couple of examples of pure & impure colour genotypes
    starting with the pure wild-type bird ie the wild Mallard or Rouen. All
    mutations are in red for ease of identification.
    A wild-type coloured/patterned drakes genotype should as we know it
    be:-
    M+/M+, Li+/Li+, e+/e+, bl+/bl+, D+/D+, Bu+/Bu+, C+/C+, s+/s+,
    B+/B+, W+/W+, r+/r+, y+/y+.

    M+ = Wild-type Mallard
    MR = Restricted Mallard
    md = Dusky mallard
    Li+ = Dark Phase
    li = Light Phase
    lih = Harlequin Phase
    e+ = not black
    E = Extended Black
    bl+ = not blue
    Bl = Blue Dilution
    D+ = not brown
    d = Brown Dilution (sex-linked)
    Bu+ = not buff
    bu = Buff Dilution (sex-linked)
    C+ = not white
    c = recessive white
    s+ = not bibbed
    S = dominant bib
    B+ = not bibbed
    b = recessive bib
    W+ = not white primaries
    w = white primaries
    r+ = not pied
    R = pied pattern
    y+ = normal yellow skin & bill colour
    Y = white skin & bill​

    thank you KK. so its a mutt. well the first case of this happening, the duckling was siblings with duskys(below)

    [​IMG]

    the 2nd time it happened was with two rouens although a chocolate muscovy could have been involed.
    look at its beak, its kinda muscovyish...
    [​IMG]
    and this time it was a mallard over a mallard pekin cross hen, shes black and white(bibbed)

    ya its more than likely a cross, reason i was confused at first was because there are a few sex-linked genes like white, brown, apricot, etc. and for some reason my mind started thinking of auto-sexing geese [​IMG]

    Tomorrow i'll draw up some punnet squares to resemble the possibilities of one of your drakes and or hens somehow carrying the buff gene.

    Hey check your other thread, rollyard just commented and said it was most likely brown dilution instead of buff and explained how it was most likely inherited.
