How often should my snake shed?

It will really depend on how often you feed your snake and the time of year. My corn snake is 5.5 feet (full grown adult) and from November-March he hardly shed but still ate every week. However once March hit he started shedding like CRAZY. I mean he is shedding 4-5 weeks and that is a lot for an adult snake. You got to realize it is spring so I don't care what you say, reptiles know when it is spring haha and they will grow a lot during that. I previously owned a carpet python and dealt with a lot of young snakes and my advice is always have a shed box in there. It won't hurt the snake and if you have it in there all the time he can go in when he wants and you should know when he is shedding. This always worked for me, however i know some people will disagree with that.
