Ditto everything Oaklands says - start with something you like the look of, as long as your fencing's good you'll be fine with Tamworths
But they are more 'inquisitive' than lop eared breeds - make sure they don't see where the food is stored
For 2 or 3 weaners you'd be looking at 20m x 20m as a minimum up to around half to a third of an acre. How you fence it depends on your plans. If you're going to rotate them to a new patch each time (handy for ground clearing and minimising the time it takes for the ground to recover once the pigs are off it) then electric fencing will probably be the most flexible. If they come from a place where they've not had electric fencing you'll need to rig up a small 'training' area - just something solid behind the electric fence, so that when they get their first shock they
have to go backwards away from it and not forwards through it or you can hold them and touch their snout to the wire (giving yourself a shock in the process
) But if they're having a permanent pen (bearing in mind what your soil is like - heavy clay and lots of rain means regular rotating of paddocks
) then stock fencing with a strand of barbed wire at the bottom works. Post and rail is another good, strong option (a wee bit more pricey) but again a strand of barbed wire round the bottom will stop them rooting under it
Whatever fencing you choose have a small area next to their arc where you can contain them for the first week or so - until they get used to you and associate you with the food bucket, this makes it so much easier to gain their trust and get them to follow you (or more precisely, the bucket
) if they ever need moved (or happen to escape
)
For your first pigs it's always worth buying them from a local, friendly breeder - one who is happy to give you advice and show you round - this means you have a local point of contact if you run into any difficulties.
As for the rare breed part - pretty much all the pig breeds are on the RBST watchlist. But Large Black & Berkshire are the rarest, so if you want to help a rare breed these would be the one's I'd advise (and I'm not biased in the slightest cos I've got Tamworths, Oxford Sandy & Blacks and Kune Kunes too
) but if you do want to ensure you're helping the breed - try to make sure it's birth notified weaners you buy, as cross breeds and offspring from unregistered pigs don't count towards the breed numbers.
I'm sure there's more I've missed, but I'm just back from a Brownie Halloween party and my head is pounding lol! I'll add any other bits when I remember them
