We have 3 Pennsylvania pink pigs this year and I made a much larger pen for them. ~150' x 100' then the little one we kept two in last year from mid May through October which was only 12' x 35'-ish. In the small pen I did a lot of shoveling and mucking out and it still got right stinky. I have heard that letting the pigs run around in a large area will make the meat tough. But I LOVE the cleanliness of the larger pen. No mucking! This pen is soil that is so sandy we have to add water daily to the mud hole or there wouldn't be one. I like that the pigs have so much fun rooting and romping and choosing to bask in the sun or sprawl in the shade, wallow in the mud hole and coat themselves with thick black mud against the biting flies, dug a nest in the sand to lounge in, or shove themselves under the rubber mats in the run-in shed. They graze on grass and weeds. They eat Poulin Pig feed. They eat our home grown tomatoes and Squashes every day and other bits of vegetable and fruit matter from the kitchen. They get a 5 gallon bucket of spent grains once a month or so from a home brewery operation. They are getting apples from our trees in New Hampshire because the Hollis Maine trees are not producing yet. I have not needed any medicines for them. I give them a few cups of Diatomaceous earth every week instead of chemical wormers. I am enjoying the lessons and stories of raising pigs at Sugar Mountain Farm. Lots of great information there--it will prompt some changes to the way we do things next year I bet--maybe even more grazing. Maybe some yogurt.
The Princes of Maine also have Miss Raychell to come play with them when we travel. She always takes the most creative photos.
