After a few batches of pigs in our barn, we decided to pursue a second barn. Identical to our first, just next door. Everything basically would be the same only flipped.
To do this we had to get a permit from the Ohio Department of Agriculture. The long drawn out process caused more than a few headaches. In the end though, the pigs are safe, they are raised at a higher standard, which produces better pigs.
Here are some photos of the process.
