I wonder about the practicality of complementing that stage of the decomposition with a free-range poultry operation. Bringing in chickens, the birds eat the larvae, and generate more fertilizer along the way.
Reminds me of some permaculture setups I've seen that do something exactly like that. There's a raised bin full of food scraps, it gets populated with fly larvae, which the chickens eat.
There are also startups that take in organic waste and use it to breed soldier fly larvae, which they then harvest and sell as protein for animal food etc.
