If your mystery gene is fibromelanosis then I'd like to participate, since I'm working on the same idea. The chicken crossing calculator says it will take >260 chickens over 3 generations to get a single stable blue egg Fm chicken, or...a lot of luck
Thanks. That's super helpful, so it's a yellow base (white skin with ID) with a hidden non-birchen color that gets diluted somehow. That's a complex one.
I guess I should clarify. Here are the linkages for some leg colors, but I can't find anything for blue. Can blue be represented by known genes?
Black - E/E and/or Fm/Fm
Buff - W+/W+ Id
Slate - e+/e+
Yellow - w/w Id
Green - e+/e+ W+/W+
Brown - ER/ER w/w
Since Bresse have white skin and their...
Hope this is the right thread for this question.
What combination of genetics give Bresse their blue feet / white skin combo? I'm especially curious since they start off yellow then turn blue over time
