    do curlies result every time u breed 2 frizzles?

    Gonna give you a bump - cause I have no idea. I thought (could very well be wrong [​IMG] ) that you should not breed two frizzles together due to the resulting chicks lacking feather or having very brittle feathers. But again, I am probably wrong - I do not have silkies, frizzles or any bird feathered like that.

    you should breed frizzle to smooth. they will hatch 50% frizzle 50%smooth

    I believe two frizzles = sizzle
    Sizzles have more brittle feathers, at least that's what I read.

    Quote:No...Breeding two frizzled birds together will give you some frizzled, some curlies, and some smooth birds. I have bred two frizzled seramas together, and the resulting curlies are adorable! Their feathers are more tightly curled, and are taking longer to fill in, compared to their siblings. They will also need more warmth in the winter in their coop, depending on where you live. If you breed a curlie to a smooth feathered bird, all the offspring will then be frizzled, rather than the usual 50/50. It is NOT recommended, however, to do this for more than one generation (frizzle x frizzle), for then you open the door to naked birds and health problems. I will have some curlied seramas available sometime in March.

    Quote:No, a sizzle has all silkie features EXCEPT for the feathering, wich is frizzled and NOT silkied.

    You're thinking of Frazzles, not Sizzles. [​IMG]

    Frazzle is the term for what you can get when crossing two Frizzled ("curly") chickens. The feathers are very brittle and will fall off, resulting in a constantly naked looking chicken.

    Silkies, sizzles, frizzles, frazzles and curlies [​IMG] Where o where is Dr. Seuss when you need him?
  9. Hi! Please read this before you consider breeding Frizzle x Frizzle:
    Anyone interested in frizzles, might enjoy this:
    In '05, I got 2 FF / homozygous / frazzled Cochin chicks in my order from IDEAL POULTRY, so I did a good bit of reading to find out what was wrong with the little birds.
    They were pitiful little things [​IMG]

    Hutt's Genetics of the Fowl
    "Secondary Effects of F.
    Since homozygous frizzles are usually more
    or less naked, except when a new coat of plumage has just been acquired,
    it is to be expected that loss of the normal insulation would cause some
    disturbances of the physiology in such birds. These have been studied in
    detail by Landauer and his associates.
    Metabolism. Benedict, Landauer, and Fox (1932) calculated that
    even at 28CC. the heat production of frizzles was greater than in normal
    fowls. At 170C. the difference was much more pronounced, and in some
    of the homozygous frizzles the heat produced was more than twice that
    of normal fowls. The loss of heat from the body surface in homozygous
    frizzles was partially offset by an abnormally low heat loss from vapori-
    zation of water, the amount of water thus lost being 30 to 35 gin. in 24
    hours per kilogram of body weight, compared with 50 to 56 gin. in normal
    fowls. The rectal temperatures of heterozygous frizzles did not differ
    from ~those of normal fowls, but at environmental temperatures below
    1500. the average rectal temperature for 10 homozygotes was slightly
    lower than in controls. One would naturally expect the homozygous
    frizzle fowls to eat more feed than normal ones in order to compensate
    for their extra heat loss, and some evidence was found that they do so.
    Other Effects. In mature, homozygous frizzles, the heart is larger and
    beats more rapidly than in normal fowls (Boas and Landauer, 1933,
    1934). The difference in females was 72 beats per minute, an increase
    of 27 per cent over the rate for normal fowls. It was attributed to the
    higher rate of metabolism in frizzles. Landauer and Upham (1936) found
    that in homozygous frizzles there was an increase over normal in the rela-
    tive weight of the heart, blood, spleen, kidneys, adrenals, pancreas, crop,
    and gizzard and in the relative capacity of the duodenum, small intes-
    tine, caeca, and large intestine. However, since the normal birds were
    Leghorns and the frizzled ones were not, it is possible that some of these
    differences might be associated with the several physiological traits by
    which Leghorns differ from other breeds (Hutt, 1941) and not caused en-
    tirely by the deficiency of plumage in the frizzled birds. According to
    Landauer and Aberle (1935), the thyroid gland and adrenals of homo-
    zygous frizzles are not normal in structure. The thyroid shows exhaus-
    tion atrophy attributed to overwork in the effort to maintain body tem-
    perature by a higher metabolism.
    Landauer (1932) maintains that the hatchability of eggs laid by
    heterozygous frizzles is subnormal and that it is still lower in eggs from
    homozygotes, but the evidence on this point is hardly conclusive.
    Significance of F and mf in Evolution.
    The gene_F isn't a desir-
    able one from the standpoint of a species trying to survive in competition
    with others. Apart from the fact that unmodified frizzles are unable to
    fly and tend to squat on the ground instead of roosting, it is clear that
    the secondary effects of the mutation are more likely to shorten life than
    to lengthen it. There are some indications that even under optimum con-
    ditions of domestication the mortality among frizzled fowls is higher than
    in normal ones. Landauer found the males to be somewhat slow in reach-
    ing sexual maturity. For all these reasons, it is highly improbable that
    the mutation could persist long in nature. Its preservation by fanciers
    is quite a different matter.
    On the other hand, the modifying gene, rnf, which to a considerable
    extent overcomes the action of F and makes the plumage almost normal,
    is a very desirable one. Perhaps this accounts for its presence in at least
    11 different breeds and varieties (Hutt, 1936). According to Fishers
    theory of the evolution of dominance, this modifying gene is exactly
    of the kind that would be preserved and accumulated under natural selec-
    tion. It is possible that a widespread distribution of it among the an-
    cestors of our domestic fowls, even before Jungle Fowls were distributed
    to the four corners of the world, may be responsible for its presence and
    prevalence in our modern breeds."
