Situation normal
If the horse is getting that cold, I would be stabling overnight with access to adlib hay (or haylage if you think he's looking a little poor), and ensuring he's rugged during the day (again with access to hay throughout the day if possible).

Oh, no - just seen your update.
Hope the horse pulls through.
