Totally makes sense but I don't raise my own feeders. I used to feed live or freshly killed but switched over to f/t years ago. I am really happy with it so far.
When I bought my snake all those years ago it seemed the prevailing consensus was to feed in a separate container. Supposedly to prevent conditioning the snake to bite when the enclosure was opened. I wasn't so worried about that aspect since I handled my snake quite a bit but I did like that it kept the mess confined to an easily cleaned bucket.
Now that she is older and seems to have lost one or more of her senses I AM feeding her in her enclosure where she is more comfortable.
