Hi there (from Suffolk). We just got our first 3 pigs, so very much still a newbie, but here's what I know so far/did:
Posts - I got 3 inch or so diameter, in the ground about 2 foot, out of the ground about 4 1/2 foot. Wire fencing between, wooden board at the bottom with barbed wire on it to discourage tunnelling under it.
Water - definitely could do a pipe in, or get a big water butt. Luckily I found a disused massive metal one and use that. Connected up to an auto-feeder with a float valve so it doesn't need anything doing to it (Unless it doesn't rain, then it needs filling every so often).
2 Pens seems like a good idea, although I've been surprised so far at how little damage our 3 have done to the land so far. That might all change though!
So far I've been buying feed from Moles Country Stores
http://www.molecountrystores.co.uk/ about £10 for 25kg bag.
Good luck with it all!

Hi there, i need a bit of help as im in the process of building a pen for our eating pigs. I have a number of questions.
A. Fence posts: what type,size,spacing and how high should the fence be.
B. Water would you run a water supply in ?
C. Thinking of building two pens to be able to rotate the land, good idea??
D. Whats the best feed with regards to ease and cost.
Many Thanks in advance
