I have four sows, we have two babies (Daisy and Tulip) who are bonded and doing really well together. Then we took in two older sows (Boss and Moo) from someone in town who didn't have time for them. They were living in a tiny cage with not much hay or fresh veggies, mostly just pellets. We attempted to bond all four pigs, and it seemed like it would work. Boss and Moo have been fine with the little girls other than the usual rumbling and bum sniffing. However Boss and Moo are not doing well together, so much so that I had to separate Moo from the other three. She has tried to attack Boss and has drawn blood. Moo is now in a 3x2 section of our main 4x5 cage. She can still see and talk to the others. Is it possible to keep this as a permanent living arrangement? I can build her a separate cage if necessary, but cannot get any more pigs to bond with her.
