Youth hunting question

I need a little help. My 13 yr old nephew want to go duck hunting. Now he doesnt have the hunter safety course yet but plans on getting it soon.

Can he come hunting with me and shoot ducks? Would the limit still be MY six ducks? Are the youth require by a curtain age to have the hunters safety course?

Any Help is appreciated. i want him to be about to experience it correctly.

He can hunt with you in a blind. He has to stay withing 'normal voice proximity' of you. You can both take a limit.
