Picky veiled. Is it common?

[ZEROPILOT]

I have 3 veiled Chameleons in 3 x large reptibreeze cages.
All three are good eaters and are active and healthy.
They eat crickets. Wax worms. Super worms, some plant material and hornworms.
All but one.
One will not (usually) eat Superworms. He will give them a look, then leave them alone. He will even pick out some kale from the same cup, meant to feed the worms.
The other two Chameleons love Superworms.
Is this normal?
Any ideas how I can make them more palatable to number 3?

I don’t see reason to worry much about it as they should just be occasional treats. Maybe try some silkworms instead.
