Dude is extremely picky, and while I would prefer he ate a staple of dubia, this stuff goes on his beloved crickets which I currently feed him 3 times a day.
In all 3 of those feedings, I dust the crickets.
I was recently looking through some Bearded Dragon sites, and even some questions on here, and have learned that I should have actually only been dusting them in 1 of those 3 feedings...
I started out making our girl crickets look like powdered donuts until I found it should be a light dusting. At least we are both on the right path now!
