I'm with you tvtaber. My girls free-range daytimes. It's astounding to me how much feed they go through -- and how stinky the coop is -- when they are occasionally shut in for a day. They are obviously getting most of their calories out in the weeds. And this is all free to me, and I don't have to clean it up.
I'm much more of the "What can they eat that doesn't cost anything?" school than the "How can I provide them with the perfect agribusinessly correct balanced ration, and darn the expense?"
Obviously, apple pomace is low in protein, and if they eat a lot of apple pomace, it may slow down their growth a bit. So what? I'm not paying for it, and I am pretty sure that free-range birds with starter/grower available ad lib are not going to die of kwashiorkor just because the apples are so yummy.
My question had to do with any known contra-indications to feeding pomace in large quantities. I could find lots about feeding it to ruminants and swine, but nothing but passing reference to poultry.
You know, like feeding huge quantities of broccoli to cows makes them explode ... well, die, anyway. It's the sort of thing you want to know about. Raisins kill dogs, parsley kills parrots, weird stuff like that.
I'll feed the pomace daytimes, outside the run, and toss leftovers on the compost, or down near the deer trails. The press is open three days a week, so that's the max I can toss them fresh stuff.
