So in March I adopted 2 boars which at adorable and they worked together perfectly. Then in august I adopted another 2 boars also a pair. After adjusting to their new home I introduced them to each other which surprisingly worked fine. Though 2 of them had occasional dominance 'performances'. Recently I got a 2 storey cage and added it onto a single (which whilst it sounds confusing, it worked). One of the older ones spent all its time in the upstairs area and wouldn't come down so I thought he may be stuck and doesnt know how to get down. But when I placed him downstairs, he looked around ans then made a dash back upstairs. I put him back down multiple times but same thing happened. A few days later I wanted to know if maybe he separated from the group so I tried putting him together with the others individualy which didn't work because they were pretty aggressive towards each other. The other 3 got along fine though. Now one of the 3 has a fungal infection (and is being treated+going to get tomorrow). Can i put the 3 together or does the infectes one need to be kept separate?
