So I currently have three boars and have been trying to bond them into a trio. I know that boar trios usually don't work, but I still want to give it a try. I currently have them in 4 x 4 c&c cage (approx 21 square feet) and they don't seem to be bickering as much. I replaced/washed all their hideys, cleaned the area around them with a diluted vinegar and water mixture, and replaced their fleece with freshly washed them. There does seem to be a bit of teeth chattering but no real fighting as one of them backs down quite easily. But really, is the cage big enough for them? I originally got another pig so I could bond with my original boar, but was then given another by a family friend who couldn't take care of them anymore. My family really wants them to be in a trio, but I'm not sure it'll work out in the future.
