nonono!!! seperating from the mother at 6 weeks is WAY to old, by then he can breed his mom, they must be seperated as soon as they start rumblestrutting(rumbling and wiggling there butt) wich is 3-4 weeks old, once they are rumble strutting they absolutly MUST be seperated no matter how old they are, rumble strtting means they are ready to breed and can and WILL breed to there mom. I have raised several litters of piggies, and know lots of people who have as well.
