Then the real scandal began. On the fourth night, instead of breaking into Patchy's enclosure again, Willy-Joel decided to shack up with the other female - a rescue pig named Charlotte, who'd previously been used in pig races at carnivals and fairs.
When Willy-Joel tried to reunite with his former girlfriend, Patchy protested. "Patchy chased him round the pen," says Nelder. "She would have nothing to do with him."
Willy-Joel and Charlotte's night of passion resulted in an unexpected situation - Charlotte was knocked up. "We were shocked and read up everything we could so we could be prepared for the birth," Nelder says. "We visited the vet and organized a roster so someone was always home. We scrubbed out and disinfected the barn and bought a heat lamp. But we're a no-breed sanctuary, so this wasn't something we had ever planned for."
