Personally I wouldn't use any method of nip training that could be interpreted by a frightened ferret as aggressive. That includes biting, smacking or scruffing. A fir NO is enough to make them realise that you don't like what they are doing and gentle handling, hand feeding and a alm manner will help them to realise that they don't need to be afraid of you. If biting is persistent then 5 minutes time out in a cat carrier where they can see you but are ignored can help. So no I wouldn't use biting.
