we just starting yes have read abit but somethings counterract one another online, we also have excellent vets who always popping in and out, also a couple of local pig farmers around us, so have alot of help we only just got them so not used to them fully yet although boar seems quite timid compared to sow who loves to be scratched. will just have to keep a close eye see if their temperment changes then ihad a feeling that they carry around 4 months so wasnt far off.
