Not to the best of my knowledge, but when making crosses, recessives often show up that are totally unanticipated. As another example, Brown Leghorn does not to my knowledge carry a gene for yellow feathers and neither do Silver Laced Wyandottes. I still wound up with a yellow hen in the F4 generation. Same with the rumpless hen. Neither parent line was rumpless and that one hen was the only rumpless I saw.Is there a trait for no tail in the wyandottes then.
Silver Wyandottes actually do probably have a cream gene. It’s pretty common for silver birds to carry dilutions that cause “golden.” However I agree that it would be unexpected to pop up.Not to the best of my knowledge, but when making crosses, recessives often show up that are totally unanticipated.

At a guess, it was a recessive in the Brown Leghorns since they trace back to blue egg laying Araucanas that carry the rumpless trait. When combined with a recessive from the SLW parents, rumpless was expressed.
But if you think white eggs, yellow feathers, or rumpless are impressive, let me tell you about the hen hatched last year that had silver laced wyandotte colors and behavior, but had a fan of long tail feathers like a leghorn. Every time I saw her with her tail fanned out, I thought of a silver laced turkey strutting around the yard.
