Not sure I have the right forum......How is the silver dilution gene expressed? I have 2 solid black roosters with silver feathers around their hackles. Is this the silver dilution coloring?? They are both from a lavender split hen and a lavender roo. These two do not have any lavender fluff anywhere. Their feathers are dark black with the blue-green sheen in the tail and wing feathers. Also from the same lavender roo, I noticed a young blue cockerel is showing the same silver hackle feathers. This roo has black, lavender-split hens. One of his girls does have a blue gene. I have bred him to these hens for a year and have gotten lavender, black, blue, and lav-split babies--but no silver hackle feathers. Thanks for any information you can give me.
