Oh, interesting. We are down to just 4 pigs at the moment, but they are all related. But we had the boar here recently and he comes from an hour's drive away. He made noises that were different to our pigs - but they were sucking tusk noises as if he was saying 'Cooorrrrrr, Giz a kissy lovvey!' We are hoping to get some new weaners in soon - probably a different breed. We'll see if there are any differences between them when they arrive if you like?
