Persistence with Vocal Coaxing and Quad Bike Failure

What happens here

The farmer continues calling the cow, observing her slow, deliberate movements. He admits trying to herd her with the quad bike earlier, but it was "ineffective" and only agitated her. He notes that the cow inches closer with each call, but is still extremely slow. He speculates she might be trying to find her calf (Cody) who has already moved to the new paddock.

Goal: Gradually encourage the cow to move while learning from previous failed attempts.
