I have a black soldier fly bin, which isn't as bad as you think it would be. Coffee grounds, and/or used pine shavings from the chickens, and then whatever scraps I don't want the chickens to have, like entrails, the heads, or any feet that had bumblefoot. Or corpses that I found an issue with, like an abscess.

They appear to scare off actual flies that bite, while not being biting flies themselves so I like that too. And I can feed the larva to the chickens, though I have to occasionally mix the stuff to keep it from going anaerobic.
I cut open the hearts to check for heartworm and then throw that to the chickens, as well as any scraps of fat that were part of, say, the head or wing (lately I haven't been saving the wings because they are so small. I am thinking of making bone stock so may skin them and throw them in the crock pot.)
I save the gizzards, livers, feet and necks in separate bags. Then I either vacuum seal the torso with legs, or I am thinking about parting out the breasts and drumsticks and keeping the rest for bone stock.
As far as loving animals or not being able to do that to them, I get it. I never thought I would be able to either. However, unless someone is vegetarian (or rather vegan because of factory farmed dairy being problematic) this is hopefully more humane. One bad day, or hour, or minute versus their entire lives being factory farmed conditions.
