Depends on their size, Ryelands can tend towards over fat very easily, so dont make good stores - its why they only tend to fetch 60-70 as a fat lamb when texel and char lambs are fetching 70-80.
If theyre close to 40Kg just send them in the fat ring, a ryeland should get somewhere close to £1.60p/kg, but if the markets well stocked with good texel crosses, expect less.
As stores expect £40/life as theyre either going to finish at a huge frame size next spring, or a tight risk of running fat early if they're fed barley to finish.
