Thanks Dogandjo, good advice.
I do love the pigs idea, but, am very vegetarian, and would really not be able to send any animal of mine off for slaughter. I'd get far too attached to them! I'm going to look into borrowing some sheep or pigs from local farmers. I'll do something about the barbed wire alright. It was put there by the people there before. I might have the ponies on the land for a short while, as yes, I think they'll run out of grass really quickly.
Cottage has two bedrooms (two up two down house!), and at the mo is in need of serious renovation, but possibly down the line I'd rent a room or do B&B.
Chickens definitely a possibility, only thing is, do they have to be attended to morning and night? I am away quite a lot with work for days at a time. Leaving cats with extra food is one thing, but never kept chickens.
Thanks again,
Tig
