So I had 3 adorable Pigs and then found one that was all alone at a pet store and fell in love with her. That was almost a month and a half ago and I have tried multiple times to integrate the new pig with the older ones who are only a few months older than the newest pig and there is always chattering and fights. Currently I have the newest pig and the other 3 in separate cages but they can still smell and hear each other so that they can familiarize themselves but it does not seem to be working.
