my last litter was of 6, yes they do take much longer so they were together much longer however we have also had a litter of 3 and they were ready by 3 weeks, we seperate as soon as they are weaned and they are all very healthy and have the perfect temperment for a little childs pet, they are calm and relaxed, the females still live with there mom, yes, but the males who were seperated at 3-4 weeks for the litter of 3 and 5-6 weeks for the litter of 6, the males are less skittish, and more outgoing and more tame, as oppsed to the girls still living with there mom, skittich, stick together, hate to handled, and they are treated exactly the same as the boys and handled just as often. oh and just cuz the male inpregnating the mom has not happend to you does not mean it cant happen, friskit was with his mom to long we though that 3 weeks was to early well guess what he DID get his mother pregnent, it CAN happen, and it HAS happend, dont take the chance.
