Free Kick - Move ball after Ready for Play?

[CruiseMan]

NCAA rules today. Late in the fourth quarter we had an obvious short kick situation. U gives the ball to the kicker who places the tee and the ball near the left inbounds line. He then returns to the huddle, the U does his checks, the R blows the Ready and the 25 seconds clocks begin.

The kicker then asks the U if he can move the ball. U responds, "You have 25 seconds".

The kicker quickly moves the ball to the other hash and they run their onside kick attempt.

So the question is...Was moving the ball to the other hash after the Ready had been blown legal?

I couldn't find a rule specifically saying he could NOT do this. I haven't checked the FED ruling yet, but I don't remember seeing anything specific about this there either.
