Oh dear, I'd start chuckling at the beginning, but very soon realised the severity of the situation. I would consider putting him in with a big strong ewe lamb as you can't leave him on his own, it would be a real shame to knock him on the head. Isolate him with a pal rehydrate him as he must be feeling really grim, trim his arse within an inch of it's life and get some fly stuff on just in case, as if he's damp from his habit he's gonna be a target to blowfly , poor little boy, I hope all goes well xx
