Answer
This is what ferrets do.  They use feces to mark territory and are often not great at litter box use.  They require a lot of free time so make sure that just because they have a big cage that you don't assume they will get enough exercise.  Make sure they use the litter box in the cage before you let them out then place them back in the cage after an hour or so.  There is never a guarantee that ferrets will always use the litter box.  Litter box use is always something I tell people about.  Try placing more boxes in the cage, try a different type of litter or spend some time training them to use the box.
