Sorry I really don't have any pictures of our pig pen...
But what we have is an addition on the end of the barn. All cement floor. With sliding doors on each side. The pigs have free range access to the outside with lots of grass and dirt and mud to forage around in...
We have one corner that we set up for there bed..With lots of hay/straw in that corner. Then we have a water bucket (55 gal. drum cut in half) for them to drink and an old mixer contraption of some sort for there food.. They seem to go to the bathroom in the opposite corner of the building as there bedding...
Outside they have a couple of kiddy pools filled with water, a few mud holes to wallow in, plenty of grass and mud to run around in....
The outside fence is actually t-posts and round wooden posts we found laying around with tin/metal siding we also found laying around here. We laid the tin on it's side length wise and made a 1/2 circle off the barn additoin.
So far so good on the pigs NOT rutting underneath the fencing. This is the second set of pigs we have had in there...Last year we had 2 (who have went to butcher) and this year we have 3 using the same area..... There is actually enough room for roughly 30-40 pigs to live there all at one time....They are a little spoiled in all the room they have....
