Oh, the only experience I have with pigs, is when I worked for the Navy on Guam, and they lived wild on the land the fuel farm (where I worked) was on. Occasional sightings, and if you were quiet, they oftentimes wouldn't see us. I'd wait until they were halfway across the road, then holler, "SOOO-EEEEE!! PIG-PIG-PIG-PIG-PIG!!" They'd take off into the boonies, like someone had set their curly tails on fire!
They're pretty self sufficient at the age you have them. Pigs are as smart and emotionally charged as smart dog breeds. They are trainable if you start early, though I eat my pigs and don't generally get very social with them. A pig will generally grow as much as you feed it. If they have access to enough food and nutrients they can get pretty big depending on the breed. As they can eat anything you can and more you should be safe after the little rooters get over 10-15 pounds.
I follow a homesteader/farmer website regular - one of the things I observe is their reluctance to expand their meat production - they buy 3-4 weaned piglets - have like 1 - 1 1/2 acres of penned woodland for them - butcher in the deep falltime ....
I reread Orwell's "Animal Farm" back during the obama regime. The parallels and similarities between the farm critters and obama's cabinet were amazingly close!
I worked most of the time at the Navy fuel "farm", in Asan. Main tank farm is there, and there's a secondary tank farm for diesel down closer to "Big Navy". Part of the maintenance department, taking care of the fuel system for bulk storage of pretty much any fuel used on the island, by the Navy and Air Force (diesel, jet fuel, etc). A total of ~65 MILLION gallons of fuel, at max capacity. I left Guam in early 2000, for a new job working for the Air Force, in Texas. The attached map will show you where I worked. Red circle was the lower compound, with pump houses and truck loading racks. Orange circle is the tank farm (see all the roads that lead to circles? those are the tops of underground fuel tanks). Yellow circle is the diesel tank farm, further south, near Big Navy.
