We feed f/t to both our Ball and Corn in separate tubs. Both were adopted, but both were also previously fed in a bin. They're docile as can be...

but they know that once they're in their tub, it's feeding time. Also, they both have wood chips, and it avoids impaction.

I only have two snakes, though which makes it easier than if I had, say, 20 or more. It'd be too much of a hassle to feed outside the tank. I don't plan on having more than 10 at any given time, so I'll continue to feed them in a separate tank.
