It seems fitting that black soldier flies like to lay their eggs where there is chicken poop. I put out my brooder cleanout into a compost bin and did not put other stuff in nor did I add water (though it was moist). Now I have a bin full of yummy free grubs that are easy to get at. Through a potato on top and they all come running, literally can pick them up by the hand full and throw them in with the chickens. It is zen like that chickens turn larvae into poop and the poop makes larvae that I feed to the chickens and get more poop. It'll stink when the summer is over and I can't get the freebies anymore. I have another bin that I use to compost veggies and it is messier to get the larvae. sometime this summer I'm getting mealworms for the winter.
