If I haven't mentioned, Chewie's should eat the crested gecko type gel (I feed a specific Chewie Diet from Leapin' Leachies and Ferry loves it - also more calcium which they need) 2-3X a week and insects 1-2X a week. I feed 2X a week insects and 2X a week gel. The insects are dusted with calcium both times and vitamins 1X a week.
This is a big difference between Chewie's and crested geckos and leachies. I don't mind feeding insects as I feed the three Leopard Geckos insects, and have a variety on hand.
