How often to train pups

I got 3 pups the same age as urs and what I do is when I go to feed them I turn them out to play and I got a bay pen that is 300 yard from there pen on the other side of the house and as there playing in the yard and stuff I clean there pen get there feed and clean water and then go looking for them I let them find them pigs there self and pretty soon when u turn them out of the pen they will hual ass straight to the bay pen that's when I know it's time to go to the next step but it may take them awhile to find the pigs and they may never u may have to just walk by the pen and then walk back but never say nothen to them or any thing this way will let u know if them pups are gamey to that's the way I do it
