Ah, sorry to hear about Delilah. I know it feels hard when she was supposed to be a keeper - we got Meg & Gaby with the intention of breeding from both but Gaby, though lovely with people, was quite aggressive with Meg and I felt it wouldn't work keeping the two of them together with piglets, so decided that Gaby had better take the one-way journey. It was hard, but Meg is so much happier not being bullied and beaten up all the time.
Poor Delilah and poor you. But you know you've made the right decision. And soon there will be Dorothy's lovely piglets to enjoy.
