I don't understand what people are referring to when they say that their chickens "waste" food from scratching it out of the feeder? Where does it go? I mean, mine will get a little on the ground but they eventually eat that too. I don't refill the feeders until they eat what they spilled. No waste. Are you filling the feeder constantly so they never "need" to eat what they spill? I have 150 pullets in one run and I have 3 30lb feeders. I have to fill them every 2-3 days. If there is still a little food in the feeder and some on the ground in the morning, I don't fill them until the evening, giving them all day to finish off the feed and pick up their mess. By the time I fill the feeder, there is nothing on the ground. In my main layers coop, the feed troughs are wood and they waste little due to the way I built them, but if I overfill the feeder, it will spill out onto the ground bellow the coop. When they are outside they still eat what was spilled, so no waste. So, why do people say they have waste? Why don't the chickens eat what they spill? Am I missing something?
