roaches for chicken feed

i just got 20 silver laced wyandotte chicks. I've also been raising tropical dubia roaches to sell to reptile and spider owners for feed. i have thousands of baby roaches that are about 1/4 in. i threw in about 20 in the chick brooder. man did they go nuts eating them! they loved it! today i threw in another 30. it was hilarious watching them fight over the roaches! its like candy to them. I've raised chickens for 25 yrs. but never realized how important a food source insects are to them. maybe its the high protein that makes them so desirable? is there such a thing as too much insects for chicks? its saving me money on chick feed as the roaches fill them quickly and hold them for the rest of the day. these roaches are fed whole grains and fruit and veggie trimmings so they're very wholesome.

I'm gradually trying to raise my chickens with no grains at all, because I don't think grains are a very large part of the diet of wild chickens (Jungle Fowl). Mine seem to prefer bugs and plants.

A common sight at grocery stores here, are eggs labeled veggie fed. It should say "these chickens were fed a diet not natural to their species".

My chicks also eat roaches, slugs and countless other insects. Every second day they don't get any feed at all and have to chase whatever they find in the orchard. They also get the occasional greens that went to seed and kitchen leftovers. Little by little I'm trying to make grain more of a supplement than the main food for them.
