How big is her enclosure? You could move her "furnishings" out of the way before you feed her, & use a shallow flat LARGE box or box lid that covers most of her floor inside her normal enclosure. Like a Sterilite "sweater box". Something that functions like a plate, but I did not mean a literal "plate". Not sure where you got "feeding rock"? It's your snake to deal with but I'd stop moving or handling her for feeding, just for best results. It's not about us "not liking" what you're doing, & for sure, all snakes don't act the same at feeding time. Apparently yours likes to "show-off"?
