One of the big reasons I want pigs, apart from getting the creeps at the thought of eating commercial pork, is to use up my extra milk and household scraps. I keep reading where potbellies will get way too fat on practically nothing, and looking at some pictures of potbellies, it's not that hard to believe. So if I do get potbellies, are they going to be able to help me out with my extra goodies, or will they get too fat? I'd really rather not deal with the regular, commercial pigs that get so huge if I can help it. Any thoughts?
