I think it’s an intriguing idea for feed. I do really like the idea of insect protein in feed, though I’ve also seen concern about prion diseases with that approach (that’s a head scratcher). If you search on BYCs you’ll find numerous threads on these whole grain diets.

Some people love them but the high cost is real, and there can be issues with birds choosing some of the food and leaving other parts behind, making it unbalanced. Some of those who like it will wet or ferment it. Aside from the whole grain element, there is the issue of feeding a layer feed to a flock that may not all be laying… I do put all of my birds on layer feed for awhile In the spring, roosters and cocks included. However I didn’t feed that for very long, not more than a few months, then I switch back to chick starter grower to give the kidneys of the non-layers a needed break.
