I left the page and just dropped it from the menus, but Google's website "slurper" scans for all pages, not just ones with links. I didn't delete the page because the gene is still present in my black/lavender flock. This year I made sexlinked Ameraucanas from cuckoo pullets and a solid black cock. And guess what popped up in a recent hatch !! A female black silkied Ameraucana chick. I know who her father is, but not her mother, so if she makes it through the winter, I can pair her with her father and should get more silkieds and the rest splits.
After several years of unintentional outcrosses to a lavender cuckoo cock I obtained from an unrelated line, at least one of my cockoo pullets is carrying the gene. I've been very impressed with the type, egg color and general vigor of the cuckoo birds, so maybe the silkied gene popping up again is a second chance.
