My chickens are 12 weeks old, and they free range. They do get free access to grower feed during the day, which they eat quite a bit. Most days I also give them oatmeal, some grapes, and sometimes spaghetti or sliced up tomato. Is that to much? I spread it out throughout the day, so they don't get it all at once. I just don't know if I'm feeding them too much.
