I started with 15 and lambed them all my first year, although I had helped an ex-neighbour with his. I agree that people often post their problems on forms - but thats their nature, its nice to have an online 'support network' when you have problems, so its a positive thing, even though it might not seem like it.
This year I have 102 ewes to lamb, so I obviously enjoy it!
So far: 10 ewes have lambed, 23 lambs on the ground, all mothered up. Only slight hiccup was my quad-bearing ewe, I fostered one onto a twin-bearing ewe as I didn't have any singles lambing at the time. No assisted births, all lambed outside.
I also think your choice of breed helps - if you are nervous, don't get breeds that need a lot if help as a matter of course. Try Lleyns, although I started with Wilts Horns because I didn't want to take on getting them sheared too. I'd be happy to recommend those breeds to anyone. If you do get easy to manage breeds, dont then manage them intensively as it defeats the object. I would start with full-mouthed ewes from an outdoor flock with a good culling policy. You know then that they have had numerous lambs, outside with no intervention, and should do the same for you. Equally, if you have just spent x thousand pounds on sheep, don't be afraid to ring the vendor for after-sales care. Most shepherds I know are only too happy to natter at length about sheep anyway.
