This is a difficult topic, but my pigs are getting on in years, with health issues, and i have been thinking, what to do when one of them passes? I cant stand the thought of one of them being lonely. I have two brothers. Can i get another boar or does it have to be a girl? Which one should be neutered? Seems like sterilizing old pig would be dangerous but will he be frustrated with an unneutered female? Advice would be much appreciated
