I’m sadly rehoming our two sows after having them for only 4 months. Our younger daughter is allergic and as much as we love them, it’s time. I’m planning on putting an ad on Craigslist or something with the pigs, food, 2x4 c and c and 4 sets of fleece liners as well as beds. About how much should I ask for them? I want to ensure they go to a good home.
