I just adopted a piggy from that rescue and she told me all about the situation. Plus, I teach at a vocational high school here in Ohio- we hear about stuff that goes on at the other schools. It's really unfortunate- the teacher is just ignorant and it never ocured to her that there was a better way.
Someone must have reported the school, because the administration is requiring her to stop breeding and selling animals. That is a good thing, but they want a quick fix to squash any bad public opinion which is where the pigs being euthanized (sp) probably comes from.
