Thanks, Robin....this was my barred roo Mr. Spock (He was already in his new home when you were there), a barred hen and the white hen...prior to being separated and put with her new white husband.
I got the barred roo from show stock and I don't think he has any mottled. I know the breeder doesn't even have mottles...only blacks and barreds. I know he bred the white hen, the mottled hen and the barred hen.
Could it be a white/barred cross? That's what he looks like...
