Conversely I do garden and do need compost, but yes it's a much better "recycling" of scraps to feed it to the birds first, rather than compost it (though I'm definitely too lazy to throw it in a food processor though... I usually opt to chop things than break out one of the processors!)
Mine...
Mine hate lettuce too. Even in winter they'd just stomp it into the ground and walk away. Like you said, it's all trial and error to find out what your flock likes.
Joke around here is that mold is the state flower. :p Plus my lot has a creek and a pond, so we have ground water just below the surface.
So far no mold issues in the run, but that's because I prioritize drainage (and I mostly provide feed inside the coop, where it stays dry and mold-free). As...
Like 3KillerBs I just toss any food scraps directly on the floor. Even if I put them in a pan the chickens will drag them from the pan onto the floor anyhow.
I sometimes go back and pick up what they don't eat, depending on what it is. Anything that might attract flies or other pests I'd pick...
So what deep litter in the run is (generally) is layered organic materials of different sizes and types, composting down in place along with the poop. As long as the run has good drainage and you have sufficient litter volume (what is the run measurements?), it's a low maintenance, low cost...
Deep litter is ideal for many runs, and conversely gravel is one of the worst choices.
Are you truly doing deep litter inside the coop, or deep bedding? Deep litter is fairly rare in the coop as it's a composting system and requires a certain amount of moisture and direct ground contact to...
