My two week old purebred silkie has something that appears to be vulture hocks. Can anybody confirm that is what they are?

I do not think this is vulture hocks. Vulture hocks are hard feathering on a Silkie and a DQ in showing. This little chick has not feathered in completely yet. Wait and see.😊

Found this with a little research online. Apparently vulture hock is recessive or possibly incomplete dominant. Jury seems to be out.
I personally have never seen it.

Feathered Leg and Vulture Hock

The Silkie breed displays ptilopody (Pti), a phenotype characterized by feathers present on the shank, feet, and toes. The Silkie also possesses the related trait known as vulture hock (V) in which feathers in the crural feather tract of the tibia are increased in length and rigidity, taking on the appearance of a flight feather (Figure 3). The presence of several Pti loci, with varying modes of inheritance, has been suggested from previous studies although the Silkie's feathered leg condition is thought to be caused by 1 or 2 incompletely dominant loci (Somes 1990b). Review of the literature on the vulture hock condition is also inconclusive with a strong indication of primarily recessive but perhaps incompletely dominant modes of inheritance conditional on the presence of Pti (Danforth 1929; Jull and Quinn 1931; Somes 1990b). A single genomic region on chromosome 13 is significantly associated with both of these traits in cross I; the SNP rs14999343 at 15.6 Mb having the highest association (Table 1). Although Pti shows a higher degree of association with rs14999343 as compared with V and has a stimulatory effect on the vulture hock phenotype, it is unclear which trait is truly associated with this region. The possibility remains of both loci being present within this region or that of V being located on a chromosome not represented in this SNP panel.
