Hello and welcoe to TAS. We're in Carnoustie, ten miles or so North of the City of Discovery, Dundee.
Dying to get out in the garden but it's still a bit early for us here.
I think rearing (as opposed to breeding) pigs is a good fit with what you're doing, but obviously depends on lots of things like your land type, access to youngstock, access to abattoir / butchery.
