From watching the video I’m most concerned that the bunnies will get hurt. The kids handling them are a bit rough, but that’s only because they handle the bunnies wrong and you need to teach them. Also humping bunnies, have you neutered and spayed them. Laughing about something that can be really stressful for a bunny and letting kids see it. That’s crossing a boarder in my opinion, especially among young children. Specially when they pick them up, a bunny can break their own back if they stomp too hard and struggling when being picked up, they can hurt themselves badly. Myself have 3 bunnies but only one is allowed to be picked up and handled by strangers. That’s only because he won’t move even though he gets picked up wrong. But I will always correct the posture so they support the bunny correct. You need to at least keep the bunny safe. I have no problem with kids handling bunnies, letting children pet and interact but at least it should be in a way that’s controlled. In a split second the bunnies can get hurt if handled wrong. They are not as sturdy like dogs and cats. But at least don’t let them pick them up. Specially in the wrong way holding them and handling them.
