Have a look around the site, does it look like the breeder cares about the pigs? Is the owner happy to show you the paperwork and gives you lots of sound information rather than just dismiss any fears you may have? Enthusiastic and caring pig owners will happily share all they know with you as they want their weaners to be treated well.
As mentioned before, are they clean? It's normal for the pigs to be covered in mud, but not faeces. And their bedding? Do they look well fed enough, is their skin ok (pigs can get mange).
How old will the weaners be when you get them? They shouldn't be younger than 8 weeks, and separated from mum beforehand (rather than suddenly taken from the family and dumped in the back of a car, stress doesn't do them any good).
Have a trawl around the internet, too, it can be very interesting.
Ask the owner what she feeds them and if you can have some of the same feed, as the change in diet may give them an upset tummy for a while, as can a sudden plentiful supply of greens (your field).
Are they outdoors at the moment?
