I feed out, I am afraid of impaction.
That varies with bedding used. Alot of us use newspaper so that's not so much of a concern.
Out is fine for some of your smaller species, though it stresses them out moving them after they eat. But I just want to be clear with larger things like burms and retics, feeding in a seperate container not only stressful to the snake, but very dangerous for the handlers as well. Just wanted to throw that in since this subject was brough up again.
