Shetlands are supposedly flighty too, which is why I gave the example of having been able to train them to food. Sorry didn't explain well enough. I think many primitive breeds have the tendency to flightiness - but it seems it can be overcome in many too.
The way to begin would be to buy lambs and keep them for a while in close quarters, til they got to know you and learned you were the source of all cake
I had my Shetlands in my goat paddock for a fortnight to begin with and that helped too.
Or, as suggested, you could have a calmer breed.
My Dad is just buying Ryelands, which I'm housing for him at present. Great soppy, fluffy things
They'd be easy to handle on a day to day basis for sure but I gather you have to be careful of getting them too fat (they
want to get fat) or else lambing can have problems - don't have any experience of that yet. My Shetlands lambed beautifully this year, despite all being first-timers.
The other thought for starting with sheep is to get whatever is the local breed. That way they'll be easy to buy, the local farmers will know about them and will be able to give you advice, and you'll be able to sell locally too. I started out like that, kept Rough Fells, very local to here, for 5 years and learned about sheep in that way.
