If he feeds of a natural forage and has a body like that, I'm going to say at least 4.5. Even in the middle of the IL. corn belt our 3.5 have a hard time putting on that much weight.
On our other properties that are in heavy agricultural regions, I would agree with the 3.5yo guess, don't know about here, though. He forages on whatever grows in the woods. There are 3 small crop fields, but only 2 that I can confidently say he would travel too. They are feeder corn fields for the cattle that live on the farm. Aside from that, this pig lives off of whats there. Receives no bait, either. I think I'm going to shoot him. I passed him up(ok, that's a lie, I couldnt get a shot off) last night. He sure does walk like a grandpa !
