Hi Countyrgirlatheart
I live on the edge of Kerry Hill country on a small Hill farm, however I keep Zwartbles at 1100ft without any problems, they winter out fine with just hay and minerals provided and shelter from hedges, we feed extra prior to lambing and after but they do give a lot to their lambs which grow very fast - so don't dismiss this breed because you think they need to be wintered in and fed lots! We recently attended the annual breed society open day at the chairmans( a vet) farm and his sheep manage to mainly winter out on grass alone on an extensive grazing system, no extra hay required except when they come in 3 weeks before lambing in January when hay is fed and supplementary feed introduced. This April we had planned to lamb outside and about half the flock did so, we just penned them at for 2 - 3 nights after, however the weather turned quite nasty so we did end up bringing the remaining ewes in at night. I think if you talked to show sheep breeders then they do tend to feed up the showing sheep to have them well covered for the shows, and they would take more feeding up then terminal breeds like texels for showing, commercial breeders seem to expect them to mainly do on grass. Their narrower heads and conformation makes them much easier lambers then texels, we have a couple of mainly texel ewes and they produce super lambs from our Zwartbles tups.
Did you see the Zwartbles at Ayr show, I sold a ewe lamb last year that was due to be shown there?
A couple of people that I have sold ewes to in Wales have had no problems with being able to borrow a Zwartbles tup, this year the society has decided to set up regional groups so I would think that through this you may be able to find someone with a tup to lend you if you didn't want to keep your own, the society also producers a year book with all the breeders listed so you could contact people local to you. AI might also be an option, and several breeders advertise in the year book, but it is a bit of an invasive process for sheep. Rams will go through a single electric fence, but if you had 2 rows of fencing a couple of metres apart then you would have a better chance of keeping them seperated.
If you start of with inlambs ewes in the autumn then you won't need to worry about a tup until next year.
Goodluck with whichever breed/s you choose!
