Well to me that sounds to me like common sence for "dont move me around."
well that sounds a little condescending... and why would an animal that has hooked teeth used for grappling strike at something it doesn't want near it?
I have been moving him to feed him since I got him and he only recently ( the last month or so) started getting aggressive before feeding
Sounds like a strong feeding response rather then "aggression". I never mess with my snakes on feeding day because they are very hungry and will look at everything like it is food (including me).
Try feeding your snake in the home enclosure. You might find that it is easier and then there is no risk of the snake biting you.
Ball pythons do bite and strike defensively. They bite quick and let go. Striking and coiling would be if they wanted to eat what they were striking at.
