Fly larvae for hens

Well, this is kind of gross. I was putting my dogs' poo into a bag and adding in some coffee grounds with the idea of breaking it down a bit before throwing it out. Flies got in it and laid eggs, and now I have a veritable sh*tload of larvae. I also have an egg-laying hen who loves larvae. My question is: should the larvae be extracted from the dog poo/coffee ground mélange and rinsed before feeding them to the hen, or should I just dump the "load" into her pen and she can pick them out herself? If the latter, is there any danger of nasty bacteria contaminating the eggs? Thanks.

They walk around on their own poop, and when they're in the yard they do god-knows-what with the dog poop in the yard. As long as you don't have any huge mounds of dookey in your coop, it's probably not a big deal.

To be fair, I put animal carcasses from my fur trapping in my chicken coop for them to eat, and they eat it all, including the intestines.

Thanks. I gave your reply a thumbs up, but I may have accidentally also clicked on the "not helpful" button. Sorry if I did.

Look up soldier flies.  There are threads about them on here.  They are a specific kind of maggot which can be started in bins and barrels.  They do not spread diseases, are not attracted to people, they eat or drive away housefly maggots, and they crawl up out of the composting mass and in a properly angled container will drop into a collecting bucket for feeding to poultry or fish.  These things are absolutely awesome in a well-designed system!  They will eat the vilest imaginable stuff, including humanure, and take a direct feed yield from it!
