position themselves and the strike directly at you or your hand, balls are very different in their defensive behavior.
A balls defensive behavior is actually moreso to curl up tightly and strike randomly, suddenly, and with short, unaimed bursts... sometimes it just looks more like a spasm than an actual strike.
This could very well be what you're seeing...
I have a group of balls that get worked up when I go in their cages... most of them strike at me when picking them up, but i've almost never been tagged by them, because of this.. the strike is usually never close enough to my hand or arm, since it wasn't really directed and aimed well... see what I mean?
By no means am I saying balls can't strike straight, or at a specific target, what I described is more of their eradict behavior when scared and/or defensive.
I've also had the rare ball that would strike straight out at me, and so much that they would jump and sort of throw themselves towards me, landing ahead of where they originally were positioned!
