Thank you. He is brighter now he has warmed up. I can only assume the diarrhoea was caused by him eating quite a few fresh apple tree leaves yesterday. It is the only possible dietary cause. The diarrhoea did not have the sinister smell of coccidiosis ( sorry) and he has not passed any for about 2 hours now. At one point it was pouring out of him.
He is still on fluids and pain relief. He has had some Fibreplex too.He has started to eat a bit of hay so I am not syringe feeding him at this stage. Hay is what he needs most.
Really thought I was going to loose him at first as he was like a floppy rag doll
