This may be the answer.
If heīs preparing to shed, itīs normal to be a bit "cranckier" (sp?).
If you fed him 2 days ago, donīt feed again so soon. Let him be for a while and at the scheduled feeding day youīll see what happens: either he is deep in shed and you just let him be (increasing humidity) or heīs not in shed and ready for a meal.
