Some ringneck snakes are easily switched onto rodents...
Some will never go for it...

Usually involves scenting.
If you feed them on a routine, to the point where they anticipate food as soon as you open the container, they may take a unscented pinky then just because they think it's food.

I had a really large northern ringneck maybe like five years ago that was around 26", she ate live unscented fuzzies I left in the enclosure.

The ringnecks that go for salamanders seem easier to get onto mice. Salamander slime must be really yummy.
