When I got my new corn (Ruby) she didn't feed and I can honestly say that it was the worst feeling, I thought I'd failed, that I was doing something wrong and I desperately wanted my baby to eat. I didn't try her again for five days and it was the hardest thing.
Five days later I dropped in a f/t pinkie and she didn't seem bothered until around 7.00pm when she was alone and things were quiet she knew what to do. For those five days I kept looking in but left her pretty much alone, I considered she may be stressed being in a new home and all of that.
Anways, I really hope things are going better...to answer your question, although I'm new to owning snakes, I'd wait until the next feeding day and hold off trying every day (I know how hard it is but hang in there)
Blessings
