This is what I read in the regs. I could be wrong, but it seems fairly clear.
You as the mentor need a hunting license. (Any license will do, not turkey specific)… Your youth needs a turkey license, stamp and turkey kill tag (zone and time period specific, or you can use it this weekend – Sat/Sun – also for the youth hunt. See page 29 of the small game/turkey regs. The law allows for your youth to avoid hunters safety, but that’s about it. He still needs a license, stamp, kill tag and needs to abide by all other laws (Ex, if he has time period D, he can only hunt that 5 day period plus the youth hunt which is this weekend.) You can’t just go out and kill a turkey any old day… Nor without a license/tag in his name.
Your youth needs to do the following, according to page 29: “Hunt within arms reach of a mentor regardless of the age of the hunter or the mentor; possess the appropriate hunting license, permits and tags; complies with all other hunting laws, seasons and bag limits…”
I would say that is pretty clear that your youth needs a turkey license/kill tag and should follow dates and laws accordingly.
