Have you tried the sachets meant for calves ? Forget the name you mix the 2 sachets together in 2 litres of warm water ? ( is it life aid ?? ) It's v good for dehydration treats calves for scour but can be given to sheep and pigs too ! I had a very weak ewe lamb from last years lambing this week , think this weather had taken it 's toll. Brought her into the shed , she just lay there I gave had teaspoons of the pink stuff every few hours , had to pour them into her mouth , then introduced some multimilk out a bottle , she was back on her feet in a day.still in shed but eating hay and nuts now and drinking fine. Good luck ! X
