I wean the kits depending on their growthdevelopment. If there is a kit thats nice, fat healthy and hogging allthe food then I'll wean it first so the smaller kits get a change toeat. However, I won't wean my kits before 6 weeks of age. I also don'tsell them until they are at least 12 weeks old.
So somewhere around 6 to 8 weeks depending on their growth development.
