I wean at 8 weeks unless they do not weigh 200 grams, then I leave them in with mom for up to another 2 weeks. I also keep them here for at least 2 weeks from the time that I separate them from mom, to make sure that they are doing well on their own.
You already asked this same question in another new thread. Please combine all your posts regarding weaning to THIS thread. It just gets too confusing when new folks start posting 100 threads asking the same thing, looking for different answers. You will get the same answers here as you got in your other thread.
