It's not that feeding in the enclosure causes aggression, it's just with conditioning the way I see it... hand -->food will turn into hand=food.

In my experience that's what happens when I gave my rats treats.. fingers in the bars were always perfectly safe until we started giving them treats through the bars. We had to open the door and give treats that way to avoid getting fingers chomped by unsuspecting friends and family.
Rats are buttheads even without conditioning.
