This is an animalbytestv vid and it talks about bad snake advice. They mention separate bin feeding at 2:10 if you want to skip to it. The info before that is interesting as well so I recommend just watching the whole thing. Their vids can be goofy at the end, but it's all in good fun.
My two cents: I don't feed in separate bins. I have 4 balls. 1 is quite picky and would not do well if it had to be moved to be fed. It seems like an endless battle trying to keep weight on him and I wouldn't want to do anything to make it worse. And in the end, it seems like a lot of work for nothing. I've been a snake keeper for almost a whole year (I know, doesn't sound like much, but a landmark for me!) and I've never been bit.
