Are you NPIP by chance? I'd be happy to hatch some in the future out of the pen that you know has a split cock bird.I have had several hatches so far this year and no silkied chicks at all yet. Will check a few more hatches before I give up and stop setting the eggs.
Is it the same gene as are found in other breeds that can have silkie feathering? Does a SiAm outcrossed to a silkie have silkie offspring? I always wanted some SiAms after I graduated and now it looks like I may never get the chance.
