Food is the first medicine. The older I get, the more I have been trying to eat more natural foods. I can't afford the high priced organic produce at the store, but I do now grow lots of the fresh food that Dear Wife and like to eat in season. Since I got a backyard flock, I have not bought any eggs at the store for almost 3 years. I don't know if my eggs are any better than the store eggs, but I like to think they are.
I have not been able to replace all our store bought foods, but we are reducing the amount of groceries we have to buy. it's a small step, but I feel good about it.
Again, using waste paper shreds in the coop as bedding, then dumping the shreds in the run along with grass clippings, leaves, and wood chips, to turn into compost, the chickens scratch and peck in the compost looking for worms and bugs to eat while adding chicken poo to enrich the compost, using that chicken run compost to feed the garden soil, the garden soil feeds the plants I grow, and we eat the produce from the plants. That's what I call a great system.
