Check out the article from the head of the SPPA in this months Backyard Poultry. He starts chicks at 6 weeks on 50% oats and claims they will learn to eat them & they don't make them fat. I know my feed guy says chickens won't eat a lot of oats, but mine seem to like them.
I saw that too. My chickens eat quite a few oats but they wouldn't be happy with 50%. They sure are individuals, eh?
