Strong opinions here, but that is what I wanted, opinions. I think we will start getting my bun used to a harness and leash as soon as he/she is settled. I will not just plop on a harness outside and expect that bunny will be fine with it, I will put it on for a few minutes indoors and if accepted offer treat and praise then work up slowly and eventually to outside, again always with supervision. I eventually want to get into agility so a harness will have to be used and accepted...and be safe. As far as using a collar goes I think I may pass on that or at least will not have one on him/her full time, the bunny collar debate seems to me like the ferret collar debate, some folks are all for it, some think it is just too dangerous. I think it also depends on the bun's personality, Hannah, my female lop would probably not have had any issue with a collar or harness, Oreo my male would have freaked at either one, Oreo was easily spooked, Hannah was mellow. We'll see how new bun reacts, if he or she freaks I will go slower or abandon the idea.
