Hi Greg,
best advice I can give you is,trawl through all the postings in this section and also the section marked "Fencing for Houdini-like JCB Digger-like Crashing Rhinos" to see what's needed. I'm confident that all the questions you have,have already been asked before on here.
You don't say where you are in the country,so difficult to direct you to the nearest pig keeping courses,but there's a few on the net. The best all-round book I can recommend is the Complete Guide to Self-Sufficiency,covers everything you need to know in general terms and gives you a good grounding to go off and get your own experience.
Housing; 3 sq metres per pig in a dry,draft-free,knee deep in straw construction.
Feed; 1lb per month old per pig per day of Farine d'Orge (french for porridge esentially) plus any spare fruit and veg.. eg 3 month old pig gets 3lb of food per day split between two feeds.
Fencing ; Galvanised sheep fencing 1m high attached to posts on the inside of the pen,posts 2m apart. Barbed wire at ground level. Two strands of electric wire,1st at 6inches and 2nd at 18inches off the ground.
Make sure you have a vet organised,feed and straw supplier sorted,all that DEFRA stuff (unknown to me,someone will advise) and an abbatoir and butcher.Ensure you have everything built,tested and ready to receive your pigs before you get them. Lastly,try to source your pigs as close to you so you have back-up in an emergency or just a guiding hand. Oh,and enjoy them,and if they're for the freezer,Don't Name them!!
Any other questions,just ask away and far more experienced than me will answer..... Ree
