It wouldn't hurt him to give him a little more nutrical, although I wonder if that is even the problem given his size, age and no history of hypoglycemia. As long as he is acting okay, his gums are a good pink color, I would just watch him, and keep him warm for now.
I know Ruby will shake if she thinks it's her bath time....lol....she stops as soon as I pick up Reno and she realizes she's safe "for now".
