Soldier fly chicken feed question

I want to make my coop like I learned in this forum where you put roadkill or whatever above the coop and the chickens eat the maggots. People are trying to say that it's a bad idea because then I will have a fly problem from attracting them. I don't think that would be true. Because the maggots will instantly be eaten and won't have a chance to turn to flies... And it's not like the flies aren't already around anyways. Can someone who has this set up tell me if this can be a problem ever and I'm wondering does it need to be extra far away from people from the stink then? Or is it not so bad??? Thank you!!

its probably more sanitary and sustainable to just grow earthworms

Green shortz DIY, living food webs, and “nature’s always right” are YouTube channels that have some pretty extensive information on black soldier flies. As well, the site”Galveston county master gardeners” has a page on black soldier flies with plenty of info. The general feeling I’ve been getting from my black soldier fly research is that they do not generate problems. When they turn into flies they don’t have mouths so they don’t land or lay eggs on food. The worst problem I’ve seen is that there is a slight pathogen problem in the larval stage but they don’t travel too far and all you need to do if you touch them is wash your hands. As well you can control the population by only letting a certain number reach fly stage (you do this by placing them in the ground away from the compost). Just don’t let the larvae reach soil until your feeding them to water you are feeding them to to limit those that continue to the next stage. But permaculture is all about sustainable cycles so do keep them breeding.

Though, I’m also still in high school and haven’t done any gardening outside of pepper plants so take what I say with a grain of salt.
