Most people on this forum, me included, will advise against feeding in their enclosure. Now with that said, I house my snake with aspen substrate so I fear her ingesting some and becoming impacted.
Also, by removing her to a separate container for feeding, I get a chance to check her out physically, weigh her and clean her viv while she isn’t in it. Plus she doesn't develop "the big hand comes in only at feeding time syndrome". So yes, I feel it is better to remove your snake to feed it.
