iv just finished training mine, just take them down to small sets 3-4 holes, and put them down, and get them used to being taken out of holes and put in holes and going through nets, once there used to that and they are confident they know its safe and you will be waiting at the top for them they will concentrate on expolring the warrens, then they will get sent of rabbits and teach them selfs. dont take them out to young as they will get kicked about by rabbits and will be scared of them, so check there faces for scrathes
