Brilliant idea Quinta. I never thought of that. I am sure insects are much healthier for chickens than grain, and would make healthier egss/chicken to eat. Keeping them alive might be difficult, and dead insects smell like... I can't even describe it. Ever smell dead crickets?
We humans should be looking into which insects and wild plants are edible. I do think very very hard times are headed our way and people will be starving.
Soon we will all be living our own little "Fear Factor" episodes in the forests when society crumbles. Eat the crickets and your prize is living another day...
