Man that is gonna be a pile of meat, you are talking about having 700-800lbs of edible pork when it is all said and done.
Only 1 is mine. The others belong to friends and family. Some of them (each hog) all belong to one family, while others were split between two families. They just reside at my place, meaning I get to feed and care for them. I consider it a hobby, so it gives me something to do around the house. I bought the 8 head feeder off of craigslist for a song. I just tapped off of my kennels for the water source. It (hog pen) is about 125' from the kennels. I've got the dogs where when I let them out, they won't even bark at the "penned hogs". Yet, when I drop them in the woods, they know what they are supposed to do. I love a dog that handles. I can't stand a dog that won't leave a caught hog alone.
