I don't, and of the three breeders in my area they all feed in the enclosure the live in, all told that is about 400 snakes. I have a WC girl ( rescue) whom is so timid will not eat if she see me during offering. If I touched her she would never eat for a few days or more.

My point is not all snakes are pragmatic enough to tolerate handling before feeding and still feed. The best chance I have of a bite is during before or after feeding. Moving my most aggressive feeder on feeding day would be almost a sure way to get bit. Generally the thought of cage aggression is believed to be a myth. I am not saying there are no other reasons for separate tub feeding but not all snakes will feed after being moved.
