Thank you both Jean and Barn Goddess, this has been so helpful and educational!
We are still new to breeding for show, so we are still learning. I know I have only scratched the surface of poultry genetics, and still have a lot to learn. I know many traits are sex linked which is why I questioned the comments on the pullets beards (color leakage tends to show up in male stock ,so maybe it was sex linked, I was hoping). They do not have any red feathers, but the beard feathers aren't shiny and don't have the green sheen you can see on the rest of the pullet's bodies. Should beard feathers have the beetle sheen like the rest of the feathers in a good black? I had been viewing b/b/s as a color family and that the outcomes were like math BB=black, Bb= blue, bb= splash. I like your argument (or very good point) that the black is diluted by the blue, and actually that explains my situation perfectly. I have a blue hen and the blue roo and both turn a brassy, dirty looking blue from sun damage. So it stands to reason that they are passing that tendency on to their offspring and I am seeing it in the beards of the pullets. But that is different to me than leakage, and I hadn't blamed it on genetics, but on my flock management choices. I have no problem with it being sun damage, I own up to that with pride. It was the fact that he thought it was genetic and linked to the gold leakage in the young roo that concerned me. I am just so happy with this first generation, they are so lovely, their type is very good, the first pullet just started laying this week and has the most beautiful egg color..... leakage to me means culling to get rid of the extra colors, I don't want to cull these girls, I am to attached/pleased with them.
So I need to replace my blue roosters with a good type black and we will be in good shape. Can the shanks on a black be to dark? Are black shanks wrong? The judge preferred the light slate blue shade my blue cockerel had at the show and said it was most correct. Do the melanizers that affect shank color also affect feather color? If I read your post correctly Barn Goddess, if my blacks are "black enough" the beards should hold up to the sun as well as the body of my birds are now? I need to buy a new SOP, I bought one off amazon and it is a reprint from 1920, which isn't helping me much .... Thanks again for all your help, I am feeling much more cheerful.
