I find Superworms and fresh greens work very well!
I raise supers and Dubia roaches. My dragons are large, long and healthy. I use Superworms as their main entree with roaches a close second choice! They get,...and love, Hornworms regularly enough! I dust their daily morning greens and summer yellow squash with supplemental powders! I used to buy 4000 crickets at a time. I spent more time tending to my flock of crickets than I did my reptiles???
When my dragons grew to over 16 inches the crickets were history!! That was a joyful day!!
There are quite a few beardie lovers/owners I know that exclusively feed Supers. A breeder friend, Charles at Tundra Dragons, only feeds supers and with great success!! It works well for my dragons and situation as well! I enjoy working with my reptiles each day,.....not so much wrangling thousands of crickets!!
Superworms and crickets both sell for 18.00 per 1000 at our local, regular animal expo every other week! Breeding supers is very easy! In 9 months time I was free of that expense forever!
Bless,
Bill
