It sounds like you are on the right path. How old is the snake? Most corns will settle down sooner or later. However, we have to keep in mind that every snake is different. You may just have a snake that will always hate to be held. I have a corn like this, and I have the best luck handling him a couple of days after he eats. Having a snake like this is great practice for any snake handler. I'll bet she has a great feeding response too!!!
