I found this chart in another thread and at the bottom it says they eat 110 grams of feed per day. That converts to almost 4 ounces per bird per day. At first I thought my birds are eating more than that, and they free range, but if you count all the chickens I have, I guess it equals out. I don't have many adults but I have a lot of teenagers, preteens and adolescents.
Does 4 ounces per day sound right?
