    Pumpkin Hulsey Color Genetics?

    The first hen could be e^b. The second hen could be a het wheaten but missing red on the shoulders/wing (pale breast) There is a documented recessive wheaten e^y. That is not what you mean, right? Any lighter "pumpkin" males?

    I guess not, hence outdated. I made a separate one for the ticked/tabby/spotted genes http://kippenjungle.nl/Overzicht.htm?run=catsimplified

    BYC Genetic/Breed Calculator Huge Task Ahead!

    The mutation responsible for pumpkin is an incomplete dominant columbian like restrictor or henny coloring factor and a recessive eumelanin diluter (black to moderate chocolate/brown). My animals are on silver, but it probably dilutes pheomelanin as well. A homozygous e+ cockerel would look like...

    She would have to show more breast. And also I realize now that a wyandotte does not have visible main tailfeathers

    Yes, I considered a wyandotte hen as well. Most difficult would be the breast not looking like fish scales.

    Hi Guys, This thread started a bit harsh but meanwhile I get a good vibe from you. I got some complaints from the Poultry Geneticists Society about the calculator. Maybe stop calling them hours at a time ;) I have been thinking about a new version of the chicken calculator and if I were you I...

    Pumpkin Hulsey Color Genetics?

    Well shank color is affected. In 2 doses the shanks get white or yellow depending on the skin color. In 1 dose you can already see the paler shank color on e+ animals. In birchen based animals less so. The chickdown of the e+ is a shaggy chipmunk but different coloration. Central stripe for...

    Pumpkin Hulsey Color Genetics?

    I have news. I worked on the suspected mutation, which I call "Dusky", for the last few years and I found out that it is an incomplete dominant columbian like restrictor or henny coloring factor. And also a recessive eumelanin diluter (black to moderate chocolate brown). My experiments are on...

    Genetics Questions about Designer Project **Parti Girls** (now defunct) (Chanties, Buckeyes, NHs, SS

    E/E without anything else is not a totally black chicken, well maybe the hens. This doesn't have to do with the degree of dominance, but has to do with additional melanizers needed being absent or incomplete.

    Cross Breeding Bantam Cochins of different Colors

    What do you mean "just white... " ;) I guess it is rec.white. Once it was believed that silkies had their own kind of rec.white and in that case rec.white 1 X rec.white 2 would give colored offspring. But that is not the current belief.
