All my snakes are on reptibark, I feed everyone in their enclosure. (beside my sand boas)
Never had a snake look at me as I was food unless I have a rat in my hand.
I thaw my rodents in baggies. If a toenail makes a hole in the bag and the rodent becomes wet, I will feed them off a plate. I will also keep an eye on that snake as it feeds.
Some snakes I'll dangle, some from hemos, some ill hold by the tail, one I have to pinch behind the neck and do the zombie rat dance, a couple I have to place on top of the hide and a couple that I have to leave the room so they will eat.
