The next couple of years will be hard for you and your family, what with illness, studies and worrying about what to do for the best. Letting someone else run the farm for a while would give you time to deal with the other stuff and sort out where you're going. Quite a few folks (particularly those on Farming Forum) would find it impossible to get their heads around farming commercially on less than 500 acres. What matters is not how much your income is but how much your income minus your outgoings are. If there's no debt attached to the farm you're up and running already. If you can keep costs down by utilising what's there already and perhaps look at a small number of high value animals rather than big numbers of low value commercial type sheep and cattle you may well be able to make a go of things. What's better for you - 25 finished commercial ram lambs at £70 a head or 5 shearling terminal sire rams at £400?
