With fermented feed they won't need much. In my big run I have 2 heavy breeds, 4 light breeds and 4 bantams and they eat probably about 3 cups of the kibbled grain layers mash I get (once fermented) a day with a few treats in the afternoon. I'm expecting that to pick up a bit once everyone is back to laying. Try and lessen the amount you put out to work out exactly what they do need and save you some money.
