We bought some land 10 miles away a couple of years ago, having looked for something closer for more than 3 yrs. For all sorts of reasons it's not feasible to move somewhere more rural at the moment (we're in South Oxfordshire but in a town) and in the end, having looked for so long, we decided to give it a try.
When we bought the land it was in an environmental scheme which means we have been extremely limited as to what we can do with it. The scheme is now coming to an end but I'm so glad we were unable to leap feet first into anything. We are taking things very slowly. We've got to know the land over several seasons and a wide variety of weather as well as knowing how long it takes in different conditions to get there. We are investing this autumn in a secure barn.
We plan to start with some chickens, electric fencing and automatic pop holes. If that goes ok I'd like to try pigs - not breeding, just raising a couple of weaners over the summer. If that works I'll try sheep the following year. I will be visiting the land at least twice a day but I do worry about security when I'm not there.
I'm optimistic that it can be made to work. I've spent the last few years reading and inwardly digesting everything small holding and animal related although I admit my practical experience is limited! I feel as ready as possible to start giving things a go but I think by taking things slowly and building up gradually I can give it a shot and if it really doesn't work for reasons I can't yet plan for, then I won't have got in too far too fast and at least I'll have given it a shot!
I realise this wouldn't work for everyone. We bought the land as a long term investment and my OH has a good, well paid job without which it wouldn't be possible at all. We didn't buy it with any ideas of making money in the short term and in fact will be losing money for years while we pay it off. But I love it there. Any free time I have, that's where I go. Sometimes you have to work hard to follow your dreams within the restraints life gives you.
Plan, plan and plan some more. Research, think things through and plan some more. But don't give up if it's what you really want to do. Just make sure you have contingencies in place and be prepared to admit to failure at even the first hint that your animal welfare is suffering.
