i've had quite a few baby corns... and honestly, some just take a bit longer to get back on food when they transition into a new home. take joe's advice and leave your corn alone for a week. then to give it more comfort and safety, instead of taking it out of the enclosure to feed it, put a plastic see through container on it's side and place the live pinkie in there (live is best). leave the pink and the snake alone... go back after an hour and see if it's eaten. if it hasn't then take a look to see where the snake is and move the plastic container close to where it is and leave the snake alone again.
if your corn doesn't eat after two hours... leave your corn alone for another 5 days and repeat this process. i've had corns wait 3 weeks before feeding but none have gone longer than 3 weeks.
i suggest you visit kathy love's site for additional info.
