Last season I hand fed all of my hatchlings for at least the first week or their first 2-3 feedings. This season I really haven't hand fed any of them except just for fun here and there and the results have been exactly the same. As long as you are using a small enclosure and a shallow food dish so that they can easily find the food they should find and eat it on their own with no problems.

If a particular gecko seems to be falling behind in growth separate it and hand feed it a few times just to make sure that it is eating the CGD. Sometimes a larger cagemate will unintentionally dominate a smaller one, getting more of the food and causing the smaller gecko not to thrive. I keep clutchmates together and only run into this every once in a while if one happened to hatch out smaller than the other and doesn't catch up in the first few weeks.
