usually breed mine off 3/4 texel ewes with an unrelated texel tup, run them with the commercial flock and they last forever!!how long do your texel tups last?mine seem to get old very quickly and if not sold shortly ,always end up dead. have no botherwith suffolks,cheviots,or even blue leicesters.what is wrong? i keep some tex/chev ewes, no problems with them dying young.clip texel tups once, sometimes twice but rarely thrice.does anyone else find this happening ?
