Hi
I am sure you will enjoy raising your lambs. I hope they do really well.
Incidentally if you wanted to keep a few adult sheep could you get a contract shepherd in to do their feet? That is what I do. There is no way I could turn my Zwartbles over(too feeble!). If I need to do just one because it is limping then I use a headstall and lift the foot as one would with a pony.
I know you have to pay but it is only a few times a year and if you ask around there is often someone willing to do a small flock for a reasonable price.
