You mean how to tell the Fey from humans? That’s just old lore. Like one of the ways to see if someone was fey was to scatter flour on the ground; they’d often have reversed feet, or bird tracks, or hoofprints instead of regular footprints.
Yes it's lore. And it's sad because in the olden days, some people believed in such lore, so children born with birth defects (extra fingers or appendages etc) or mental defects, were feared to be Fey, and they were marginalized from society if not altogether murdered.
