I've had this problem with my new corns, even after a month. I offer them food and if they don't take it I will leave it in their hide. If they don't eat it overnight I put them in a small breathable container with a tight lid for a few hours and usually they'll eat. If that doesn't work you can split the head of its food and leave it in the habitat in the hide. These all have worked well for me. If these don't work I would contact a vet who specializes in reptiles. Also if their skin starts to wrinkle I increase the humidity in their habitat. If they haven't shed for a couple of days after that I will put them in a tight container with a damp paper towel to help shed for about 30 mins to an hour. They usually shed after that. Then I feed them the day after. Good luck!
