My larger snakes just lay in a tight coil for a moment after being picked up - not the traditional ball. My little ones used to ball, but have just decided to be nippy lately instead. I wish they would ball up. I prefer it to being struck at
Once I get them in my hands, they are usually fine, again, with the exception of my little girl - the hatchling who is the most defensive. She'll strike in my hands. She's getting a bit better with each feeding, though, and I'm sure will mellow out over time.
