Beardies will choose supers over crickets most of the time. Just remember that supers are not really a staple they should be used with other feeders but not alone. Supplements don't stick to them very well either.
My girls would only eat supers if I let them. Zak prefers them over any other feeders, but Wheezie won't eat them he eats other feeders so for them it levels out. So they still get a balanced diet.
For the rest of my beardies I make them eat other varieties of feeders and just use the supers like a desert.
None of my beardies would touch crickets after about 8 months of age. An a couple have never liked them. I personally haven't had any crickets in the house sense March and man I like that.
All in all you have to show them who the parent is. :wink: They don't always want what's best for them just like having kids. :lol:
