Fibro Sex-link Project help

[ParksPoultry]

I’ve crossed my roo with a few different hens to get very sweet little sex-links. It’s been pretty consistent and reliable. I finally hatched some chicks crossed with my fibro roo over white leghorn hens. The result consfused me. The chicks are very sweet, white with black spots, but the skin/shanks are light with black spots. The melanin seems to be “blending” which should indicate female, but it’s still very confusing. One of the crosses hatched all black! I have had chicks that have darkened over time and chicks that were very dark at hatch. I’m selling some chicks but I don’t want to mislabel their sex.

I’m also assuming offspring that are crossed back to the rooster will not be sex-links if the hen had dark skin and the rooster does as well?

I’d appreciate if a more knowledgeable/educated person than me could take a look. Tell me what you think!

What is your question? What sex chromosome gene are you trying to use?

What is your question? What sex chromosome gene are you trying to use?

I was trying to use the melanated skin for sex-linking. It was my understanding that females would inherit the rooster’s dark skin if their mother had light skin.
