Bag limits for the Youth Hunt include total bag limits for the entire season. The Chattanoogan has a story along with this reminder about ages:
Only youths, ages 6 through 16 (as long as they have not reached their 17th birthday), may participate, regardless of whether they possess a Junior or Adult license. Each youth must be accompanied by a nonhunting adult, 18 years or older, who does not need a license but must also wear 500-square inches of fluorescent orange.
Youth hunters ages 10 – 16 need a hunter education card along with the appropriate license where applicable. Those, ages 6 – 9, are not required to possess a hunter education card or license.
