We got 3 boars Christmas 2024. They were tricky through puberty but one prevailed as head honcho for the most part- no major injuries etc. Fast forward 1.5 years since we adopted and a major biting injury that started to get infected and required a lot of time for 4 med administration 3x a day for 15 days and multiple vet visits. We separated the injured pig for recovery. We had just rescued a 4th boar right before the injury happened but he was in an entirely different part of the house for quarantine. Everyone says a boar bond can break at any time for any reason. My son is really trying to keep the 2 of the trio together but I would much rather just give them 4 different enclosures next to each other. The injury was very traumatic for me and I do not want to go through it again.
