A friend of mine actually does take a ferret hunting. It cleans up all the rodents in short order, but then he has to cage it or it will go hunting on its own. He also uses a pair to hunt rabbits. One stays in the cage and he turns the other one loose in rabbit thickets and hunts the clearings with his longbow. When the rabbits realize a ferret is in the area, they move to the open where he can shoot them. The loose ferret will come back to the caged one. Sorry, wandered off the subject...
