Best way to start young pups?!

I just let mine run loose and run what ever they want. Rather it be deer rabbits hogs etc etc.
Every now and then I'll let them bay in a pen with an older loose baying dog but I don't put them in a pen much.
When they get bout 8 months old I'll start hunting them with a older dog that's going good. After bout two or three good hog hunting trips I start breaking them off of trash.
Prolly not the best way but i think it makes the pups more independent because I'm not always around when they are hunting...
