I'm in the thinking stages. Here are my thoughts... 2 pigs to raise for the summer and butcher in the fall. Pen made of livestock panels supported by t-posts in an area I want to use as more garden next year. Electric wire around bottom of pen to keep them from rooting out. Pen size 32x32 big enough? I understand they don't need much shelter except some shade in summer? Will they outgrow this size pen before butchering time and be hard to keep penned up?
