Baby ball pythons twitching?

So one of my clutches they all twitch usually only when someone walks up to the tubs. I'm thinking it's just a defensive thing but I've never seen it before they all had their first meal today with no problem. Was just wondering if anyone knows what this is or if someone experienced this with their snakes. Thanks in advanced!

Do you mean like they flinch when they see you move, or like twitching that they can't control? If it's the first one, they're probably just skittish and it isn't a problem.
