Similar like grass fed beef and dairy is a sign of quality and "naturality". I look forward to the day when insect fed chicken becomes a sign of quality. Because insects are part of a natural diet for chickens.

It's actually a welfare issue for chickens. They have feathers, and they molt. Just like hair, feathers need methionine. Methionine is very hard to get solely from plant sources. If they don't get enough methionine they eat each other's feathers, not just the discarded feathers (which left on their own they do normally).
If the insects are fed naturally, it would probably be more cost effective to feed the chickens whatever you are feeding the insects. The only reason to introduce the insects would be if you were using something the chicken cannot eat, like wood.
