I never understood the 3/4 cup statement. Crumbles & pellets are going to weigh a different amount, so a cup of pellets is a different amount than a cup of crumbles. Case in point, my feed barrel can fit 100 lbs. of crumble, but only about 70-80 lbs. of pellets. I have always seen it stated that a hen will eat ,25 - .33 lb. of feed per day on average depending on size. Cup measurements do not enter into it.
