I know this is an old thread, but I'm wondering if any of you are still around and might chime in with how things panned out. Two of our silver Appleyards were completely white/yellow. Below is a picture of them a couple days post hatch. They had no black anywhere (no dark mohawk or tail feathers).
They are now over four weeks post hatch, and these two still have no dark markings on them at all--just the same whitish-yellow, while their brothers and sisters are all developing lots of coloration. You can see the difference in coloration toward the end of this video. That video was at just about four weeks post hatch.
We are so curious about these two. Any more experienced folks care to share your experiences?
Thanks!
