I go through a bag of feed a week (40 pound) I have 18 chickens, 6 guinea's and 6 ducks - the ducks are little pigs!
In summer time it drops ALOT, there are so many bugs to chase and eat they don't have HALF as much time to stand around the feeder.
My chickens get leftovers and scratch twice a day.
