After doing a little investigative work, this is the most plausible scenario I can conjure. CAL Ranch is located in the states of ID, UT, AZ, and NV. It seems they now go through Hoovers but this bird certainly didn't come from there. There is a hatchery located in Caldwell, ID called Dunlaps Poultry that is the only if not one of the only hatcheries that carries Silver Pencilled Rock Bantams. They carry no other breed remotely similar. OP, are you near this hatchery by any chance? I have to go with it just happening to have the wrong leg color! I can't think of another breed that would appear similar without it being more wrong than just leg color
