Gotcha! I knew about the sex-link with choc over black hen but wasn't sure what the reverse did. Hadn't thot about it actually...lol
Now I just need to figure where blue fits in. It covers chocolate but not black, right? That's why my black & blue flock throws chocolate & lilac. The blue drake carries chocolate & are the hens blue/blue or blue/choc? I haven't paid attention to the sex of my choc babies.
your blue drake had to be carrying chocolate. It's how I ended up with a lilac hen from you. Your hens are blue. Your blue drake carrying chocolate over your blue hens will produce black, chocolate, blue, lilac, lavender, and silver. Lavender is chocolate with 1 blue copy and lilac is chocolate with 2 blue copies. A lilac bird is actually silver with chocolate and a lavender is blue with chocolate. A plain chocolate is a black bird with chocolate. Of course females only need 1 chocolate gene to show it while males need 2. If a hen isn't visually chocolate, then she can't carry chocolate.
If you have no hens carrying chocolate, then you will only get pullets that can be chocolate. Some males may carry chocolate but of course won't show it cause you don't have 2 chocolate or chocolate carrying birds breeding. It doesn't matter what the main color of the bird is whether it is black, blue, or silver. Females always pass chocolate to the male, a visually chocolate male will always pass on chocolate to the female and the male both. Just remember it only takes 1 gene foe females and 2 for males to visually be chocolate.
