Most people say its normal for juveniles to be restless while being held.
My 500g pied is a freak when being held, he is always stretched out, trying to find somewhere to explore or hide. My little 200g het pied girls are calm as can be and will just chill on my lap with im on the computer. They wont even ball up, they just seem comfy.
So I think it just kinda depends on the snake in my opinion.
