Depends on the buries in question. Are they near hazards, close to fences, etc. You don't want to sicken her with lost causes. Let her watch what is happening and when you have a decent bury out in the open, then you let her off. You can always let netted rabbits go errr free in the open
most of the burys are open mate by the way dropped rabbits dont work for me so that would be a nono
