as long as they are eating it on their own you don't need to hand feed them unless you just want to. last season i hand fed all of my hatchlings the first few times that i offered cgd, or until i could see that they were eating it on their own. this season i have only hand fed a few that i wasn't sure if they were eating it on their own yet and that has worked fine.

it can be a little trickier if you get your geckos from someone who didn't feed cgd as they will try to hold out for whatever they used to get but i have yet to have a gecko that didn't switch over within a few weeks time.
