Soy and other beans can also just be boiled, instead of roasted.
I wouldn't be looking at grains to boost protein, because the amino acid profile is lacking. I'd focus more on legumes that complement grains and animal protein, fish, worms and bugs that are more complete proteins.
The red worms used for composting can also be fed to chickens. Vermiculture or vermicomposting is very popular and easy to do.
Some of what you're looking for, like the heat treated soy and mineral mixes, can be found at feed mills. There is also fish meal available that can be added, for additional protein. http://www.fertrell.com/poultry.html
I would definitely keep oyster shell available at all times. Egg shells can be baked and then crushed, before being offered. I think the baking makes them safer for storage.
Your chickens would be getting a lot of vitamins and minerals from all the different fresh foods you are planning to feed. I'm not sure how much supplementing you'd really need to do. It's different if they're only getting a grain based food with some soy in it. That's why those types of feeds need a vitamin and mineral mix added. Calcium would be needed in a larger amount than what is in many of the fresh foods, depending on what you feed, but that's what the oyster shell is for.
Foods to stay away from that are safe for us to eat are chocolate, avocado and anything with caffeine.
