For some reason I'm still confused on how much and how often to feed FF. Is feeding 1/2-1 cup per chicken 3 times a day OK? How do I know if their full? Should their be some food leftover? Does a full crop at the end of the day mean they have had enough to eat? Can they over eat, I'm worried about fatty liver syndrome. And does anyone have tips on feeding FF to chicks? All help is appreciated, thanks.
