Our dog gets sweet potato/quinoa mix some days and raw chicken with bones other days (1-2x a week). We raise our own broilers so all the necks, gizzards, hearts, lungs extra meat goes to her. She loves it and it seems to be helping her itchies.
We built one earlier this spring for growing crops for us to eat and we love it. We were eating salads in April. Delish. Very easy to construct. We used James Prigionis plans. He has videos on youtube.
