I had problems with some of my babys too. I have them in 6 qt tubs from animalplastics, originally used paper towel as substrate, and only one hide. I switched to cypress mulch and added another hide for all the baby tubs and waited a few days to let them settle in to the changes. ALL of the ones who wouldnt eat at all just jumped on the hoppers i threw in, and most of the ones who were already eating switched over to f/t. For mine, it was just a sense of security I guess. I was going to suggest live feeders too, but everybody else beat me to it. Hope it works out for you.
