I used fermented feed for awhile and have debated about going back to it. Perhaps in the summer, but truthfully it SMELLS HORRIFIC and im not sure how id keep it from freezing in winter. I cant really tell you how to make chicken feed from scratch, but im really good with human food. Im 5 years cancer free this upcoming February, so ive completely changed how i eat. My birds eat a lot of my leftovers, so that intake is super healthy, and get my garden scraps. Right now they eat the mash from my local co-op. Lots of soy, and ive been wanting to change their diet like i said, but thinking come spring ill hunt for local, non gmo, soy free food stuff.
