I know many Corn Snake owners who feed their snakes in a feeding bin properly, for the entire life of the snake, without a single problem. Once I passed the 6th Corn acquisition, it became too cumbersome. And when I added in several different species, I expanded my knowledge base, and I've never bothered again.
The pros for corns, who are very active when in hand:
-they associate the bin with feeding and get down to business when placed in it.
-no chance of substrate ingestion.
-no mouse mess (blood, squished out feces) in your viv.
-no chance of a "wrapped and dragged" that was never actually eaten smelling up the entire room and "germifying" the viv.
-they never associate opening the door with feeding.
Feeding in a separate bin would not work for many species, like GTP's and most BPs, for example.
And just like the bin and eating becomes a conditioned response, I have found that other responses can be conditioned. Sauza, for example, uses a twisted paper towel to boop the snoot, so Caesar knows it's NOT feeding time. I now do that, too, and it works for every species I have.
