It's really easy to get a water dragon to hand feed. Just be careful, because once he gets into the habit, he won't want to go back to hunting his own crickets. Trust me.

Be patient. Start with holding him a little each day without food, until he's comfortable with you. Then around feeding time, pick him up and hold some food out to him. He'll eat it once he trusts you. If he's really young, though, watch out for your fingers. He may nip them in his eagerness to get to the food.

Dark-Side, it's probably not a good thing to feed him bugs out of your yard, but Praying Mantises are pretty easily available. You can order them online to put in your garden, I think. According to Snopes.com (I love that site), the Praying Mantis fines seem to be a myth, so you probably don't have to worry about that.

I don't know how they'd do as a staple food for Water Dragons, but they'd probably be a good treat.

lol dont worry about me catching outside bugs they spray the area im in way too much
where I used to live though was far away from anyone and was mostly unusable land they no was allowed to build on so the state owns most of it and just lets it sit they dont even spray for mosquito out there thats why i'd think about catching a snack maybe once inawhile there but still prob wouldnt
currently I am thinking about breeding crickets I had some hatch in his tank when he was in his old tank so doesnt seem hard to get them to lay and hatch from what i've heard the hard part is getting them from babies to a size to eat

-edit-
read the page on the praying mantis guess it is legal, i do kinda wish there were ones where I am now there cool bugs to look at
