Don't bother, just make sure you keep it crutched.
Swaledale ewes aren't tailed as they need the woolly protection for their growing udders over winter. Some farms clip the appropriate region a week or so before tupping, to be sure the tup doesn't stub himself
or miss.
As lambs, they mostly do just fine, but you have to be vigilant about mucky bottoms and get at them with the clippers straight away.
