Glad you have them eating well, even if it means gecko tails.
Actually, cresties eat a powdered food that's mixed with water. They're frugiferous, and eat Allen Repashy's Crested Gecko Diet. It's a complete diet, so insects aren't necessary, although most people do give insects & worms as a treat.
As soon as they hatch and I get them into their new box, I give them a little dab of the diet on their noses, so they get a taste of what's for dinner.
So, there's really no running around and hand-feeding.
This year, I have 12 females breeding, and some are first-timers, so I'm getting mixed results with eggs. A lot of duds. They lay 2 eggs every 28 to 45 days or so, and I have 30 some eggs incubating, 12 or so hatchlings, and more on the way until about October.
They're really THE BEST starter herp. No special heating/lighting required, no insects or rodents, and easy to care for!
Every time one of the geckos drops a tail (doesn't happen very often-but it does happen), I think of you and your babies...too bad they can't be frozen and shipped out to you for your kids.
