Pets Corner in Harlow has some some 5 months old females that he is desperate to move because of space. I do volunteer work there.
I know he doesn't register his pigs and they are Essex Saddlebacks which isn't recognised as a separate breed. They aren't cross breeds though.
Sorry, that sounds more complicated than it is, its just I got annihilated by posting I had Essex Saddlebacks once, apparently its a controversial topic to some piggy people.
