We are tired of the chicken food going to waste, so we only put a scoop into the feeder right before bedtime (they'll eat it when they wake up, before we let them out) and give them a scoop when they come looking hungry for food, or to lure them with a mix of treats and feed to lock them into their run if we're leaving for a while.
Our problem has been the birds DECLINING to eat the feed, favoring the forage method of eating grass seed, weed leaves, toads, bugs, worms, grubs and more spiders than I thought we had.
Our other problem was the chipmunks gorging on the (ignored) chicken feed. On one hand, I resented the money wasted on good purina feed which the chickens decline to eat, on the other hand, I feel sorry for the chipmunk who will be eating high protein, high calcium feed all winter which he's stored in his nest somewhere under my garage and agonizing over his new kidney stones.
We prefer the Purina Layena Pellets for grown chickens, the crumbles make them cough and sneeze. Also the crumbles I think might be better as a mash for babies, mixed in small batches with water. We call that "baby mushies" and our chickens consider that a treat.
When our chickens were younger they earned the nickname Little Monkeys for all their antics on the waterer and feeder. The heated waterer was usually unplugged by morning...
