Human scent on feeders

[MarkL]

This was youth hunting weekend in TX, so I went hunting with my youth and the .357 Mag carbine he uses. We got to the stand at about 3:30 Saturday afternoon and checked the feeder to make sure it still had corn and tested the timer, then set up in the stand.

We observed a single spike approach the feeder. It wandered around the area for a minute, then wandered off without eating any corn, or even getting close enough to do so.

A little while later, a group of three deer approached the feeder but never got closer than 10 yards before turning away.

Could the deer have been spooked by residual human scent left on/around the feeder?
