~I attempted to go the route of the comercial dry foods...a long time ago. Last year, when I had 30+ hatchlings, I would soak the dry food in apple juice and toss it in with their veggies. Some ate it, some didn't....most couldn't be bothered. So, I ended up feeding it to my crickets....they loved it! I figured that was one way of getting the ingredients into my dragons.
~Some breeders, though very few, call their lizards "Bug Free"..meaning they are started out with the dry stuff. I have had many, many types of lizards and none of them preferred the dry food to the "Real Thing"...so, I stick to the tried and true. Yes, it is more work and makes for higher maintenence, but the results have been worth it. Anyone who has purchased any of my dragons can tell you they are healthy and do well. I suppose it would be like always eating everything except a good home-cooked meal.
~As far as getting dragons, etc. to eat veggies, I chop the greens up very fine, throw in some finely chopped up fruits and toss in some "hobbled" crickets and mealworms. In the act of grabbing at the live food, my dragons, inadvertently, would get some salad in the deal. Eventually, they caught on that it wasn't so bad. I also found that ALL the dragons I have ever owned were crazy about prickly pear fruit. They also looked kind of cute with "lipstick" on from the stain of the fruit.
~Up to about 10 weeks old, I found something a little quirky with alot of my dragons. They would wait until the greens were dry and crispy...and THEN they would eat them. I haven't a clue why, but I have heard of others doing it.
Good Luck,
