I will add my opinion now, ive done all 4 options available when my jills have come into season,breeding a no no why have all the unwanted litters ,jab made all the jills scream so i assume it must have been a tad painful,leaving in season nearly lost one of my best jills to infection never again ,snipped hob all the way worth every penny and never have to worry about my jills ,he lives with them and castrated hobs all the time all get on well and the hob does his job . but i suppose its all down to preference but i would recommened get a hob snipped to everyone
