Hi and welcome to YT! It probably is un-normal. He's had a lot going on in little world. He will probably not eat since his tummy was upset from the car ride. Make sure that he has plenty of fresh water available. Also, do you have nutrical on hand? Just in case he should still not want to eat.
You should go to the health and diet section and read up on different types of food. I am not expert but there is a lot of better foods that kibbles and bits. Also be careful of too much things like luncheon meats...hubby give ours little treats here and there and they love it, but the do tend to get a little spoiled when I try to feed them dinner dinner time.
He will settle down in a couple of days and be running around like crazy I'm sure.
Just give him some time to adjust. Puppies will tend sleep alot. Mine would play,play and play and all of a sudden just decide to lay down and go to sleep, lol. Enjoy the ride and welcome little Beau. Can't wait to see pictures.
