How many pigs did you have on two acres nnbreeder? I am only keeping these porkers for 6 may be 7 months. Mainly because it gets very very wet up here and it would not be a happy life for them. Last time it rained all day they did not come out of there ark (pig home) only for food. I am thinking about may be planting some root or veg for next years pair this autumn an you never know I may get to eat something. At the moment I have 1/2 acre (not rubbing you nose in it honest Knight Family) split into two and when they muck up this 1/4 of an acre I am going to move them into the next. After 5 weeks it looks like they may stay on the first 1/4 for the whole length of time. I have a small area of native rhizome reproducing grass, similar slightly to Johnson Grass, its a common pointer ill drained soil and is a member of the Juncus family. Anyway they love rooting in there but are not eating the rhizomes
Next year I will be looking at getting a darker skinned breed as I have to keep an eye on the weather forecast and apply factor 40 to there ears on sunny days. They as yet do not like water being splashed on them or like wallowing in mud!!!!!!
nicchick or anyone else that is considering pigs I keep mine surrounded but an 3 wire 60cm electric fence run by a 12v battery and so far they have complete respect for the fence.

Knight Family have you considered approaching someone in your area that has land may be wooded and you could rent it and use pork as a payment?
