    WHEN BREEDING WHITE FRIZZLE COCHINS
    The main thin is to only have pure bred white cochins and pure bred white frizzle cochins to breed with.
    Then to pick each year ONLY THE BEST BREEDERS. I did not keep CULL BIRDS, BUT DISPOSED OF ALL CULLS FROM DAY ONE OF HATCHIG.
    (1) AS TO BREEDERS: Only selected birds that the feather quality was good and, white.
    NO DISCOLORED FEATHERS OF ANY KIND, those were culled as soon as I could see their feathers growing out as chicks.
    OR CULLED FOR ANY OTHER DEFECT AS CHICKS.
    (2) Nopw as to picking adults,
    (A) the birds have to have broad backs.
    (B) the bird have o have the correct beak, face, leg, feet coloring fo white cochins.
    (3) now to apply the ABA standard for this correct correctness.
    IE: ABA is American Bantam Association standard which in color now.
    (A) Put name int brower and AB facebook site will come p:
    (B) You can join and also buy a new Standard for Bantams and Bantam Ducks


    Now for Breeding WHITE COCHIN FRIZZLES:
    well having bred frizzle cochins for several decades:
    I would not breed frizzle to frizzle.
    The "smooths" that come from a regular feathered ,
    are the ones used in the f-1 mating.
    #! Are Of father to daughter.
    #2
    @matings are mother to son.


    (A)I always used the smooth females to my frizzle roosters.

    (B)I showed both the female frizzles and male frizzles.

    (C) The smooths are very important to the mating of frizzles.

    (D) when using the frizzle to frizzle you get the extreme frizzles,
    and will eventually breed the feathers off the birds.


    (E) the feather folicles will not be in the skin.

    (F) the chick will have curliest tight feathers and by the third molt not have many feathers at all.

    (G)these extreme frizzles make for birds that can't stand the cold or the heat and have to be culled.

    (G) the fact that if one breeds the frizzles long enough to each other,
    you breed the feather follicles OFF,
    ie:the holes in the skin for the frizzle feather to come out FF.


    (I)I know I tried it before I learned how to breed good frizzles.

    (J) Frizzles have a modifying Gene which allows their feathers to curl forward.
    (K) I had a pullet that had not more than 20 feathers on her whole body so she was a waster. I figured out quick??


    (L) That is WHY Do I take the time to feed and house birds.
    I was going to kill 1/4 of them in the end.


    (M) So I went to using only smooths out of frizzles and regular frizzles.

    (N) that way I got 1/2 frizzles of good quality and 1/2 smooths to breed with.

    (O) I personally liked my frizzle males for breeding to the smooth females.
    As the smooth females had better type than the smooth males.


    (P) I never liked a long legged cochin male

    (Q) And I showed my female frizzles as well as the frizzle males.

    (R) Never had the brittle feathers that people speak of Just had them lose the places(folicle holes) for feathers to grow into the body with.

    (S) But frizzles get a tight curled narrow wet looking feather if you breed frizzle to frizzle too long.

    (T) Here is a friend of mine from Australia that explains the modifying gene in frizzles.

    KazJaps from Australia

    here is a Frizzle modifying gene (mf) that alters the ___expression of Frizzling (F). This might explain Glendas results.
    Put these genes together in different combinations & youll get various expressions of frizzling (or no frizzling).
    A bird may appear not to be frizzled, but may actually have the frizzle modifying gene masking ___expression (heterozygous for frizzling & homozygous for frizzle modifier
    Ff+ mfmf). So the phenotype (how a bird looks) is non-frizzled, but genetically they have the frizzle gene.


    Glenda puts it nicely, Smooth Frizzle. The bird actually has one dose of the frizzle gene. Therefore offspring of 2 seemingly normal-feathered birds may produce a Frizzle (by the modifying gene becoming heterozygous or the frizzle gene becoming homozygous).

    So, there are 5 main phenotypes (how a bird looks)
    1: normal feathering (f+f+ Mf+Mf+ or f+f+ mfmf)
    2: smooths, as Glenda calls them (Ff+ mfmf)
    3: exhibition frizzles (Ff+ Mf+Mf+)
    4: frizzled, less woolly than extreme (FF mfmf)
    5: extreme frizzling (FF Mf+Mf+)


    f+ = non-frizzled gene (wild type)
    F = frizzle gene (incomplete dominant)
    mf = modifying frizzle gene (recessive)


    Mf+ = non-modifying frizzle gene (wild type)
    FF = homozygous frizzle (2 doses of the frizzle gene)
    Ff+ = heterozygous frizzle (1 dose of the frizzle gene)


    mfmf = homozygous modifying frizzle (2 doses of the modifying frizzle gene)

    * The modifying gene needs two copies (homozygous) for ___expression, plus the frizzle gene.

    The frizzle gene needs at least one copy for ___expression, plus not homozygous for modifying genes (if heterozygous for frizzling Ff+).

    So, as Glenda explained, if you breed two smoothies together (Ff+ mfmf X Ff+ mfmf), there is still the possibility of getting frizzled birds (FF mfmf), about 25%.

    Also breeding a smoothie (Ff+ mfmf) with a normal feathered bird (wild type f+f+ Mf+Mf+) will produce frizzle (Ff+ Mf+mf), & so on.

    The frizzle modifying gene apparently is quite common in non-frizzled birds.

    Well, thats the theory anyway.

    This thread is a perfect example why I like to listen to people who have bred birds for decades. It is not very common for poultry geneticists to have identified a modifying gene such as this.
