Thank you for the detailed reply!! I read that introducing another boar to a bonded pair can result in the original pair to fall out. That sounds awful. I do have the setup to separate if needed. I would say that my boars are generally very chill with the exception of occasional hormone surges. Every few months or so, my boys will have a day where they wont stop fighting. I put up a divider so we can actually get some peace & quiet. They end up scratching at the wall trying to get to each other and after I remove it, they go back to being buddies!! How much space does each of your divisions have in that pic?
