hey buddy! The weaning stage once it gets out of the mother is around 4 weeks. Day 1 of the 5th week is the perfect time to remove them. As a fact, you should know that they can start breeding (and you'll know earlier than 28 days if they do.) In my case, I'd separate them and wait til they're around 8 weeks old and i put them back together to do the nasty. haha You can keep the youngsters with the adults but do try to stick with 1 gender if you're not planning on breeding them. If you don't, even the male youngsters would mate with the mom and that's just no good. Hope i got most of it bud!
