I adopted three boars from a local animal sanctuary at 12 weeks. They came together as they are brothers, but very obviously different characters. From the start it was obvious Snowdrop was Boss Hog - chasing and drrr-ing. He's gradually got more agressive and at 5 months he continues to chase Nigel (the smallest pig), although he'll tolerate Buzz (middle pig). A fortnight ago, when I came to put them in their carrier to go to the vet for neutering, a full on fight erupted (enclosed unfamiliar space I guess). I managed to separate them, but Nigel was bitten. I hoped that the neutering would calm them down. They are still co-habiting in a large 4'x2' two-storey hutch and outdoor run, establishing their own 'zones'. Buzz seems to tolerate either brother, but Snowdrop continues to chase Nigel, chatter his teeth and sway, and though he grows plumper and healthier, Nigel is not thriving in the same way. I noticed today another bite on his rump. Should I continue to give these two a chance or should I separate them? Any advice please?
