My friend just took one of my three week old boars. She has a bonded pair of 3 month old brothers. One pig (Apple) was showing normal dominance (rumble strutting, mounting, nipping at neck). His brother (Jack) is trying to get in between of the baby (Captain) and Apple. Now the bonded pair are going at it. Now the brothers are teeth chattering and lunging at each other. My friend is a mess and is not sure what to do. Any insight?
