Thank you all. She's had 2 different wormers : cydectin (strong) and panacur, hep p'd, fluked, clicked and combivited and even kaolin and morphine.
Perhaps you're right Sally, she was just fluked 7 days ago. Thanks foobar, when can I fluke her again - in a month? All the rest seem fine though, nice dry bums.
She's happy in herself and with the rest of the group, not isolating herself, yet.
I'll google your suggestions posters. Did call vet this morning who says I have done everything and there's not much else I can do. It may be a liver / copper related thing but we have been doing everything by the book totally in that respect so there's not much else we can do, time will tell.
And after spending about £300 on lab results on our last ronaldsay death on new year's day, I'm not lab resulting any more.
Maybe I should just buy myself some tasty hybrids
must say (and this will please you Sally), out of the 3 primitive breeds we keep, soay, ronaldsay and castlemilk moorits, the moorits are most healthy and robust beautiful sheep (well, that's cheating, they're not primitives actually, just rare breeds). Have considered just keeping a flock of them but they have lovely long legs that are so good at jumping even high dry stone dykes
Thanks posters, I will report back in a bit, it's always good hearing someone's learning experiences.
