Bigfoot, he's Mille Fleur D'uccle/OEGB X Silkie.
How can Bigfoot have two copies of the Vulture Hocks gene, if one of his parents is a Silkie?Bigfoot has Vulture Hocks, he has two copies.
Everything I can find about Silkies says they are not allowed to have Vulture Hocks, and are disqualified in a show if they do have them.
So if the Silkie has no Vulture Hocks gene, then Bigfoot could not possibly have TWO copies of the gene. (And if the Silkie does have Vulture Hocks, then it is not a good-quality Silkie.)
