Baby snake "substrate" question

[Railrider1920]

I always preferred to feed outside of the main enclosure, in a tub of some sort. That way the snakes get used to being picked up and taken out of the tank. Then feed them in a tub with no substrate. If you feed them in the main tank, they think that their going to get fed every time the top is opened. I don't know if that is correct, but that's what I remember anyhow.
