People make things more complicated than they need to be when it comes to hogs and farrowing. They need a dry, wind free, well bedded area and they don't care how nice it looks. In fact the nicer it looks the more effort they seem to put into tearing it up. Here is about as basic of a farrowing shed as you can get in the video. And last nights litter makes #100 in this shed. Made it from junk wood and scrap tin 9 years ago, and a lot of sows and piglets have rotated in and out of it since then.
