We feed all but one of our snakes in their home enclosures (13 ball pythons, 1 boa, 1 milksnake). All seem most comfortable and most confident while hunting in an area that is their "home" territory and since we feed live we want that sort of situation for them. Like Robin mentioned, our snakes are usually primed and ready to go on feeding night and I'd rather not stick my hand in there and shift them to another enclosure when they are obviously in strike positions and looking for food (especially not with 3,000 gram plus Brannagh LOL).

There's nothing bad or good though about feeding in or out of their enclosures. It's just another feeding decision that people have to make with their snakes. As long as it's based on good decision making and knowledge, it's all good.
