I'm so sorry about the piglets. I admire all the effort you put into saving them, though, and everything you've done for Poptart-----love that name.
It will take quite awhile to get Poptart tame----one of my females won't even let me touch her. Her former owners gave her lots of attention when she wa little and inside, but when she got too big, they put her outside in a pen and basically ignored her for a few months before I got her. She's outside now with my 2 other PBPs, and I don't give her a LOT of attention, but she at least gets close to me now. Good luck, and keep us updated on your progress with Poptart.
