Hello and welcome from me in South Lanarkshire

I can't give a lot of advice on the chickens as, like you, only have them for eggs at present - but I believe hubbards are a good choice.
For your pigs - you'll need your CPH holding number and a herd number before you start. Have a look on SEERAD's website and contact your local animal health office for the herd number - the property may have a CPH number already if it's not part of a larger holding that's being sold. If you can get yourself on a pig keeping course that would be a good start, but there aren't too many this side of the border. Alternatively a couple of good books on pig keeping (I like Starting with pigs by Andy Case) a friendly local pig keeper and this forum will keep you on the straight and narrow. 5 acres gives plenty of room

for weaners, fattening for the freezer you don't want to give them too much room (it'll take longer to get them to weight) half an acre is more than enough for 3-4 I'd reckon. You'll need good fencing with a strand of barbed wire around the bottom or for moveable fences (good when you're rotating) two strands of electric tape at about 8 and 20 inches from the ground should contain them (notice I say
should, have a read through the old posts about escaping pigs!) A shelter or arc - if you're only raising them Spring - Autumn (which for weaners is ideal, avoid keeping them over winter with all the rain we get up here - it's not fun trailing out to them twice a day in the mud!) a temporary affair made from bales of hay would suffice or you can invest in a more permanent arc.
If there's anything else you need to know just ask away, we're just outside Lesmahagow and have a couple of Kune kunes, you're welcome to visit and see my piggies and get a feel for them, cup of tea waiting - just pm me if you fancy it.
