They can't be raised with domestics from what I've seen. Domestics could die. That said, after several generations of captive breeding on your place, they will probably each develop immunity to the other. I kept my domestic pigs on the other side of my property from my wild pigs and I fed my domestics first or tended them first. I used boot washes when I left the wild pen. At times I forgot and probably took some dirt from the wild pen to the domestics and never had problems. I've known two people who penned them together and lost their domestics because of itjackie c said:Thanks Marcia, I'd like to try one or two, maybe next year. Can they be raised with domestics? And how big do they get?
