When you notice they're in shed once, you'll never forget. My babies usually shed once every month to month and a half. Whenever they're due for a shed I usually check their bellies. Their bellies and lower side dull out so much it gets pretty easy to identify once you know what to look for. With some more experience you'll get a better eye for it. Another good indicator is most of them refuse meals but not all when they're nearing a shed.
