Yes, that also doesn't look like vulture hocks to me. Vulture hocks are long, stiff, dragging feathers that look and feel very similar to wing feathers. They're a disqualification for Cochins so I've had to familiarize myself with what to look out for with my Cochin bantams.
Remember that there are several leg feathering genes (3 or 4 beyond vulture hocks I think, I never remember the exact number off the top of my head) that all generally impact a different portion of the leg and in slightly different amounts. The feather elongation you're seeing at the hock is one of those genes, not true vulture hocks. None of the pictures you've posted so far are true vulture hocks.
