OfBug is already working on this, selling larvae for farmers who want to start raising insects as a protein source for their animals. http://www.ofbug.com/animalfeed
It would be fun to experiment with modular units that you raise insects in. You'd keep a pipeline of bugs in various stages of development. Then, when it's time to feed the chickens, take a module, open it up for the chickens, and watch the fun! Maybe the bug container could be made of heavy paper so it could be cheap and biodegrade quickly. Or it could be something reusable like a bucket. (That's so simple I don't think it counts as an idea. But if someone figures out a good system, they'll surely be able to turn it into a book/product line/service. Maybe they'll go to work for the UN trying to get everyone to do it.)
Of course, rotating the chickens across vast pastures a la Joel Salatin is probably the ideal way to provide fresh daily bugs as far as chicken nutrition and land management is concerned.
