I think the times you have to worry about where you feed, is when you have a non eater. I know with my first one, feeding was iffy in the feed box. I switched to feeding in the cage, and I notice a much stronger feeding response. Although if you still get a strong response, while feeding in a separate enclosure, then you're fine. It's just when you don't that you need to reconsider your feeding routine. Find what works for you and your snakes, and go with that.
