BH reckons the Swaledale will be the last breed standing - but if any of you tell any of his farming friends he said that, he'll deny it hotly, lol.
His reason is that the Swale ewe can carry any kind of lamb, is hardy, thrifty, milky and a good mother - so she will always have a job.
Downsides are that pure Swale tup lambs don't make much; will never be other than 'poor' conformation and take a while to reach slaughter size. So unless you want to direct market the most beautiful hogget meat in the world
, you won't make much out of the boy lambs.
The other issue, of course, is the Old Boys' Network and how difficult it would be for a newcomer to break into that. If you work on a farm you probably know all about that
and would realise you need to select one or more top breeders as your mentors and suppliers of your initial ewes and tups
