try and find someone with proven working ferrets to tag along with or invite them to your perm, then let your ferret follow the experienced one around, you will both learn doing this, also if you was doing a 200 yard hedgerow using only 1 ferret, then the rabbits are probably giving the ferret the run around, get yourself another Jill, not only will they both work better as a pair, but also ferrets are best kept with another ferret for company
