Hiya
You sound just like me!! I had wanted to be a vet when I was younger and had spent a few easter holidays lambing.
Last year I bought 20 LLyen ewes in lamb, all at least having had one crop of lambs so at least they knew what they were doing
This year I bought a tup, kept all my ewe lambs and have put 6 to the tub this year, keeping the rest to sell as gimmers next year. I have 18 ewes left from the original lot - put 2 ewes down the road
Just bought some more so I have 40 running with my tup right now!!
I have reg pure breeds bought due to the breed having easy lambing characteristics and good maternal instincts. Had v few problems to be honest, ewes lambed without many problems, wedders made a good price when sold and they were sold of grass. The second pick are being fed lamb finisher at the moment to get them fat. Neither myself or my other halfs family consisting mainly of farmers have had any experience with your choice of breed so can't offer any advice on that.
I just bought 10 gimmers at £90 each and 1 crop ewes for £70, 2 crop for £65. Our tup was 1200 gns as they sell rams up here in gns rather than £, think that is case everywhere.
Unless you can get your ewes in lamb by AI or can borrow a tup that only had a few to cover then your only option is to buy a tup, I think.........
As for feed mine are on grass all year except at lambing when they get cake and sugar beet but I have loads of grass and lamb finisher to get them fat if needed.
