Dennis - have you tried taking this fawn completly off of the milk or replacer that you are using for a day? You can keep it hydrated with sub-cu fluids, but sometimes, if they have a sour belly or an enteritis of some sort, the last thing they need is more stuff being put into their stomachs. But, they will be hungry or thirsty, so they will try to eat a little, which only compounds the problem. Just a thought, sounds like you are throwing everything out there at it. Good luck.
