Hi folks. So I've a Lleyn X Welsh ewe who has been sick ever since lambing late April. Scouring, lost all condition, poor milk yield. Unfortunately she had a difficult lambing and her lamb eventually died. I have tried two courses of antibiotics (Alamycin and Pen & Strep), have wormed her twice, and fluked her separately (on vets advice). She has all sorts of licks, and I have even tried drenching her with natural yoghurt. She's in the Hepvac program as well. She's still on her feet and seems happiest being kept with the rest of the flock, she comes over and has a nibble of cake every day, she's otherwise alert and bright, and is eating grass. But she looks a bag of bones and is still scouring badly. I was hoping she might 'come good' after all this treatment, but not so far. What do you think would be the kindest/most economically viable thing to do with her at this point?
