No, it's not stupid, for a long time the conventional wisdom was that feeding in the enclosure caused cage aggression. I can tell you right now that there is no way I would even attempt to move my larger boas from their enclosures into a "feeding tub" when the smell of feeders is in the air. They have very strong feeding responses and are ready to strike as soon as the door opens. When it's not feeding day I open the door and they don't even twitch, they know the difference.
